Those skilled in the art will appreciate that the application environment shown in fig. 1 is only a partial scenario related to the present application, and does not constitute a limitation on the application environment of the present application.
In some embodiments, as shown in fig. 2, a method for quickly designing an information chart is provided, which may be executed by a terminal or a server, or may be executed by the terminal and the server together, and the method is applied to the server 104 in fig. 1, for example, and includes the following steps:
at least one target elemental image group is determined, step 202.
The information image is an image obtained by layout design of text or data, can more intuitively display the data, is an image carrier for information visualization, and can be at least one of an electronic slide show, a poster or a propaganda picture album. The information image includes a plurality of information elements, the information elements are graphic elements with semantic information in the information image, including numbers, icons, texts, titles and the like, and the numbers can be digital numbers, such as: 01. 02 or 03, also can be alphabetic numbers, such as: A. b or C. The information element groups are obtained by grouping information elements in the information image, wherein one information element group comprises at least one information element, at least one information element refers to one or more information elements, and a plurality of information elements refer to at least two information elements. The information elements may also be referred to as visual elements, so the information element groups may also be referred to as visual element groups. The appearances of the information elements included in the respective information element groups are not uniform, but the layout structures of the information element groups are uniform, for example, assuming that two information element groups are included in one information image, the layout structures of the two information element groups are both: 1 icon and 1 text, the icon being located to the left of the text.
The target element image group is composed of element images of the information elements in the target information element group, and can be segmented from the target information image. The target information image comprises at least one target information element group, and one target information element group corresponds to one target element image group. The element image is an image area corresponding to the information element, and is obtained by dividing the information image.
Specifically, the server may acquire the target information image, for example, may receive the target information image sent by the terminal, may acquire the target information image from the local database, and then group the information elements in the target information image to obtain at least one target information element group. The server divides the element images of the information elements in each target information element group from the target information images to obtain target element image groups corresponding to each target information element group respectively. As shown in fig. 3, the information elements in the target information image are grouped to obtain 4 target information element groups, and 4 target element image groups are divided from the target information image, each target information element group including 1 number, 1 icon, and 1 text.
In some embodiments, the server may perform element detection on the information elements in the target information image to obtain element detection frames and element types of the information elements in the information image, and then group the information elements in the target information image according to the element detection frames and the element types of the information elements to obtain at least one target information element group. The element detection frame is obtained by detecting the information elements in the information image and is used for marking the positions of the information elements in the information image, and one element detection frame comprises one information element. The element type includes at least one of a number, text, icon, or title.
Step 204, determining a candidate information image set; each candidate information image in the candidate information image set corresponds to at least one element image group, and the element image groups of the candidate information images are obtained by grouping and dividing information elements in the candidate information images.
The candidate information image set includes a plurality of candidate information images, which may also be referred to as an information image library. The candidate information image comprises at least one information element group, one information element group corresponds to one element image group, and the element image group of the candidate information image is obtained by grouping and dividing the information elements in the candidate information image and can be called as a candidate element image group.
Specifically, each candidate information image in the candidate information image set corresponds to at least one candidate element image group, the server stores the candidate information image set and at least one candidate element image group corresponding to each candidate information image respectively, and the server can store respective background images of each candidate information image. The background image of the candidate information image is an image obtained by removing information elements in the candidate information image. The process of obtaining at least one candidate element image group corresponding to the candidate information image may refer to the step of obtaining at least one target element image group, which is not described herein.
In some embodiments, after the at least one candidate element image group is segmented from the candidate information image, the candidate information image may be split into images composed of two different layers, the first layer being the layer in which the at least one element image group of the candidate information image is located, and the second layer being the background image of the candidate information image. Background images refer to non-data graphics, also referred to as visual background, that act as container-holding elements in the design.
Step 206, for each candidate information image in the candidate information image set, determining a degree of matching of the candidate information image with at least one target element image group based on the element image group of the candidate information image.
Wherein the degree of matching characterizes whether the layout structure of the at least one elemental image group of the candidate information image is consistent with the layout structure of the at least one target elemental image group. The degree of matching may be a state, for example, the degree of matching may include matching and non-matching; the degree of matching may also be a value expressed in percent.
Specifically, the server may determine layout information of at least one target element image group to obtain first layout information, determine layout information of at least one candidate element image group of the candidate information image for each candidate information image in the candidate information image set to obtain second layout information, determine a degree of matching between the candidate information image and the at least one target element image group based on the first layout information and the second layout information, for example, determine that the degree of matching between the candidate information image and the at least one target element image group is the matching if the first layout information and the second layout information are identical; in the case where the first layout information and the second layout information are not identical, it is determined that the degree of matching between the candidate information image and the at least one target element image group is not matching. Wherein the layout information characterizes a layout structure of at least one element image group including the number of element image groups, the types of the respective element images constituting the element image groups, and the positional relationship between the respective element images.
Step 208, determining a matching information image from the candidate information image set based on the degree of matching.
The matching information images are determined from the candidate information image set based on the matching degree, and may be one or a plurality of matching information images. The element image groups of the matching information image may be referred to as matching element image groups, the number of matching element image groups in the matching information image is identical to the number of target element image groups, and the layout structure of each matching element image group is identical to the layout structure of the target element image group.
Specifically, for each candidate information image, the server may determine the candidate information image whose matching degree satisfies a preset matching requirement as a matching information image. The preset matching requirement is preset, for example, the preset matching requirement may be that the matching degree is matching, provided that the matching degree includes matching and non-matching; the degree of matching is assumed to be the degree of similarity between the first layout information and the second layout information, and a predetermined number of matching information images may be determined from the plurality of candidate information images in order of the degree of matching from large to small, the predetermined number being a predetermined integer, for example, 5.
Step 210, combining each target element image group and the matching information image to obtain a generated information image.
The generated information image is an image obtained by combining the target element image group and a background image of the matched information image, and may be an editable multi-layer image, for example, the generated information image may include two layers, a first layer is a layer where the target element image group is located, a second layer is a background image, the first layer is placed above the second layer, and any element image in the target element image group may be scaled, rotated and moved in the first layer of the generated information image.
Specifically, the server may determine a background image of the matching information image, which is obtained by removing the information elements in the matching information image, and may be stored in the server in advance. And then the server combines the target element image groups with the background images of the matching information images, and places the target element image groups in the background images according to the corresponding positions of the matching element image groups in the matching information images to obtain the generated information images. As shown in fig. 3, the 4 target element image groups are placed in the background image according to the corresponding positions of the 4 matching element image groups in the matching information image, resulting in the generated information image.
In the information chart rapid design method, since the information images can comprise data presented in a table form or data presented in an image form, the information images can also be called as information charts, the candidate information image sets are determined by determining at least one target element image group, the matching degree of the candidate information images and the at least one target element image group is determined based on the element image groups of the candidate information images for each candidate information image in the candidate information image sets, the matching information images are determined from the candidate information image sets based on the matching degree, and then the target element image groups and the matching information images are combined, so that the generated information images are automatically obtained without manual drawing, a design sketch is provided for the design of the information images, and the efficiency of the information chart design is improved.
In some embodiments, the above information chart rapid design method is adopted to obtain an interactive tool, which may be called a paste, and the user may select an information element image group from an information element image library or submit a target information image, and then the tool may automatically search the database for the background images of the matched information images, so that they may be rapidly converted into a design draft of a new information image.
In some embodiments, the step 202 of determining at least one target element image group comprises: responding to an image generation instruction, and acquiring a target information image; the image generation instruction carries a target information image; grouping information elements in the target information image to obtain at least one target information element group; and dividing element images of information elements in each target information element group from the target information images to obtain target element image groups corresponding to each target information element group.
Wherein the image generation instruction is for instructing to obtain the generated information image using the target information element group.
Specifically, the terminal acquires the target information image in response to the image generation operation, and transmits an image generation instruction carrying the target information image to the server. The server receives the image generation instruction, acquires the target information image from the image generation instruction, and detects and groups the information elements in the target information image to obtain at least one information element group. The server may divide the element image of the information element in each target information element group from the target information image, to obtain a target element image group corresponding to each target information element group. The server may then return at least one target element image group to the terminal. The terminal may present the received target element image.
In some embodiments, the server stores therein a library of elemental image combinations, and the at least one target elemental image group may be further determined from the library of elemental image combinations, where the library of elemental image combinations stores therein a plurality of elemental image combinations, and respective elemental combination identifications of the elemental image combinations, one elemental image combination including the at least one elemental image group. The terminal responds to the image generation operation, acquires a target element combination identifier from an element image selection area, and sends an image generation instruction carrying the target element combination identifier to the server, wherein the element image selection area is an area for selecting the target element image identifier from a plurality of element image identifiers. And the server responds to the image generation instruction, determines the element image combination corresponding to the target element combination identifier from the element image combination library, and obtains at least one target element image group.
In this embodiment, at least one target information element group is obtained by grouping information elements in the target information image, and then the element images of the information elements in each target information element group are segmented from the target information image, so that automatic extraction of the information elements in the target information image is realized, a reusable element image is obtained, and materials are provided for the design of the information image.
In some embodiments, grouping information elements in the target information image to obtain at least one target information element group includes: detecting information elements in the target information image to obtain element detection frames and element types of the information elements in the target information image; for each element detection frame, determining an image area with the position consistent with the position of the element detection frame in the initial transition image to obtain an image area matched with the element detection frame; determining a filling color value according to the element type of the element detection frame, and filling an image area matched with the element detection frame according to the filling color value to obtain a target transition image; grouping each filling image area in the target transition image to obtain at least one filling image area group; filling an image area refers to the result of color filling the image area; and determining element detection frames corresponding to the filling image areas in the filling image area group, and forming the information elements of the determined element detection frames into a target information element group.
The element detection frame is obtained by detecting the information elements in the information image and is used for marking the positions of the information elements in the information image, and one element detection frame comprises one information element. The element type includes at least one of a number, text, icon, or title. The initial transition image may be a blank image, the size of the initial transition image being consistent with the size of the target information image. The filling color value is determined according to the element type, different element types correspond to different filling color values, and the filling color value is used for carrying out color filling on the image area matched with each element detection frame in the initial transition image. The image area in which the element detection frame matches is an image area which coincides with the position of the element detection frame in the initial transition image and is surrounded by the element detection frame. The target transition image is an image obtained by color filling the initial transition image and is used for grouping detection, the target transition image comprises a plurality of filling image areas, and the filling image area group is obtained by grouping all the filling image areas.
In particular, the obtaining of the at least one target information element group may be divided into three steps: the first step, the server can input the target information image into a trained information element detection network to detect, so as to obtain respective element detection frames and element types of the information elements in the target information image. And secondly, aiming at each element detection frame, the server can determine an image area with the position consistent with the position of the element detection frame in the initial transition image to obtain an image area matched with the element detection frame, determine a filling color value according to the element type of the information element to which the element detection frame belongs, and perform color filling on the image area matched with the element detection frame according to the filling color value to obtain the target transition image. Thirdly, the server can input the target transition image into a trained grouping detection network for grouping detection to obtain at least one filling image region group, and for each filling image region group, the server can determine element detection frames corresponding to filling image regions in the filling image region group respectively, and form information element groups of the element detection frames into a target information element group to obtain at least one target information element group. Wherein the trained information element detection network is used for detecting the positions and element types of the information elements in the information image, and the trained grouping detection network is used for grouping the information elements.
For example, as shown in fig. 4A, in a first step, the information image, i.e., (a) in fig. 4A, is input to a trained information Element detection network to detect, for example, may be input to an Element-YOLO network, and an Element detection box and an Element type of each information Element are marked in the output information image, for example, an Element type of an information Element in an Element detection box marked with "35" in (b) in fig. 4A is text, and it is understood that the text content in the figure is schematic content; secondly, performing color filling on the initial transition image according to the element detection frame and the element type of each information element in the information image to obtain a target transition image, as shown in (c) in fig. 4A; third, the target transition image is input into a trained packet detection network for grouping, for example, the target transition image may be input into a Group-YOLO network, which is obtained by training on the basis of an Element-YOLO network, and the output image is marked with a packet detection frame for each filling image region Group, as shown in (d) in fig. 4A.
For example, as shown in fig. 4B, an information image of an information element group having the same layout structure is illustrated, and (a) in fig. 4B and (c) in fig. 4B are two information images having different appearances, respectively, it is understood that text contents in the figures are schematic contents, and as can be seen from (B) in fig. 4B and (d) in fig. 4B, the layout structures of the information element groups in the two information images are identical, and each information element includes 1 icon and 1 text. It is apparent that the layout structure of (a) in fig. 4B and (a) in fig. 4C is not uniform, and each information element group in (a) in fig. 4C includes 1 number, 1 text, and 1 icon.
In the embodiment, the filling color value is determined according to the element type of the element detection frame, and the image area matched with the element detection frame is filled according to the filling color value to obtain the target transition image, so that each information element in the information image is automatically grouped by using the target transition image, any texture and color interference is eliminated in the grouping process, only the structure and layout of the information element are focused, and the accuracy of information element grouping is improved.
In some embodiments, determining the degree of matching of the candidate information image with the at least one target set of elemental images based on the set of elemental images of the candidate information image comprises: determining layout information of at least one target element image group to obtain first layout information; determining layout information of the element image group of the candidate information image to obtain second layout information; a degree of matching of the candidate information image with the at least one target element image group is determined based on a degree of similarity between the first layout information and the second layout information.
Wherein the first layout information refers to the layout information of at least one target element image group, and the second layout information refers to the layout information of at least one element image group of the candidate information image.
Specifically, in the case where the similarity of the first layout information and the second layout information is greater than the similarity threshold, the server may determine that the degree of matching of the candidate information image and the at least one target element image group is matching; and determining that the matching degree of the candidate information image and the at least one target element image group is not matching in the case that the similarity between the first layout information and the second layout information is smaller than a similarity threshold value.
In some embodiments, the server may determine the number of target element image groups, the element types of the element images in each target element image group, and the positional relationship between the element images in the target element image groups, to obtain layout information of at least one target element image group, that is, the first layout information, for example, the first layout information may be: the number of the element image groups is 3, and one element image group comprises 1 icon and 1 text, and the icons are positioned on the left side of the text.
In this embodiment, the matching degree of the candidate information image and the at least one target element image group is determined based on the similarity between the first layout information and the second layout information, so that a basis is provided for determining the matching information image of the at least one target element image group.
In some embodiments, combining each set of target element images with the matching information image to obtain the generated information image includes: determining a background image of the matching information image; the background image is an image obtained by removing information elements from the matched information image; and combining each target element image group with the background image to obtain a generated information image.
Specifically, the server may store a background image library including background images of each candidate information image in the candidate information image set. After the server determines the matching information image, the server can directly acquire the background image corresponding to the matching information image from the background image library, and then for each target element image group, the server can integrate each element image in the corresponding target element image group at the position of each matching element image group in the background image to obtain the generated information image.
In this embodiment, since there may be a plurality of matching information images, by determining the background image of the matching information image, and combining each target element image group with the background image, editable generated information images can be generated quickly and in batches, and efficiency of information graph design is improved.
In some embodiments, determining the background image of the matching information image comprises: determining background color values of each information element group in the matching information image respectively in the matching information image; for each background color value, determining color difference values between the color values of all pixel points in the matching information image and the background color values respectively, and forming pixel points with the color difference value smaller than a preset threshold value into pixel point clusters corresponding to the background color values; generating a mask image corresponding to each background color value respectively; in the mask image, the color value of each pixel in the pixel cluster is a first color value, and the color value of the pixel outside the pixel cluster in the mask image is a second color value; and determining pixel points of each information element in the information element group based on the mask image corresponding to the background color value, and updating the color value of the pixel point of each information element in the information element group in the matching information image to the background color value to obtain the background image of the matching information image.
Where the background image refers to a non-data graphic, also referred to as a visual background, that acts as a container containment element in the design. For example, as shown in fig. 5A, two levels of visual background are designed in the information image, three information element groups are respectively located in the three different color values of the visual background of the arrow shape, and the three information element groups and the three arrow shapes are placed in one larger visual background, i.e., the texture background layer, and the two levels of visual background constitute the background image of the information image. More complex information charts can be generated by stacking visual backgrounds step by step.
The background color value is determined from the matching information image, and the background color value corresponding to each information element group can be the same or different. The first color value and the second color value are used to generate a mask image, the first color value being different from the second color value, e.g., the first color value may be 255 and the second color value may be 0. The background color value corresponds to a pixel point cluster, and the pixel point cluster is formed by pixel points, wherein the color difference value between the pixel point cluster and the background color value in the matching information image is smaller than a preset threshold value.
Specifically, the server may group the information elements in the matching information image to obtain at least one matching information element group. For each matching information element group, the server can extract the color value of any pixel point in the grouping detection frame of the matching information element group in the matching information image as the background color value of the matching information element group, then clustering the color values of all the pixel points in the matching information image by taking the background color value of each matching information element group as a clustering seed to obtain pixel point clusters corresponding to all the background color values. For each background color value, the server may update the color value of each pixel point in the pixel point cluster in the matching information image to a first color value, and update the color value of the pixel point outside the pixel point cluster to a second color value, so as to obtain mask images corresponding to the background color values respectively. For the mask image corresponding to each background color value, the server may determine, from the matching information image, the pixel points where the information elements in the matching information element group corresponding to the background color value are located, and then update the color values of the pixel points to the background color value, so as to obtain the background image of the matching information image.
In some embodiments, the server further needs to perform image preprocessing on the matching information image before determining the background image of the matching information image, the image preprocessing including the steps of: 1) Firstly, carrying out color quantization on the matched information images, reducing the number of colors in the images, wherein each information image can be effectively represented by 128 different colors; 2) The processed picture is converted from RGB color space to HSV (Hue, saturation, value) color space, represented by three dimensions of Hue, saturation, and Value.
For example, as shown in fig. 5B, a schematic diagram of a process for determining a background image of an information image is shown, and it can be understood that the information elements in the input image in fig. 5B are schematic information elements, and the information elements in the actually processed image, such as text content, are more complex. Firstly, carrying out image preprocessing on an input information image, then carrying out information element detection and grouping on the preprocessed information image to obtain grouping detection frames of information element groups in the information image, and extracting a color value in each grouping detection frame to be used as a clustering seed in K-means. For better clustering, the global background color value may also be used as a cluster seed, i.e. the number of clusters K is equal to the number of packets plus one, as shown in fig. 5B, for a total of 7 different background color values, k=7. In the clustering process, the distance between pixels is added into three channels H, S, V as a weight, and meanwhile, the difference value in the H channel can be enhanced by 20 times in a mode that the hue channel is closer to the human visual perception color, so that different hues with the same saturation are more likely to be gathered into different categories. And then respectively constructing a binary image mask for each pixel cluster obtained by clustering, and carrying out binary image complementation by using a hole filling mode in order to obtain a complete visual background consistent with the original information image.
In this embodiment, a pixel point cluster corresponding to a background color value of each information element group is obtained, a mask image corresponding to each background color value is generated, pixels of each information element in the information element group are determined based on the mask image corresponding to the background color value, and the color value of each pixel of each information element in the information element group in the matching information image is updated to the background color value, so that a background image of the matching information image is obtained quickly, and the generating efficiency of the background image is improved.
In some embodiments, determining the background image of the matching information image further comprises: determining background color values of each information element in the matching information image respectively; for each background color value, determining color difference values between the color values of all pixel points in the matching information image and the background color values respectively, and forming pixel points with the color difference value smaller than a preset threshold value into pixel point clusters corresponding to the background color values; generating a mask image corresponding to each background color value respectively; in the mask image, the color value of each pixel in the pixel cluster is a first color value, and the color value of the pixel outside the pixel cluster in the mask image is a second color value; and determining pixel points of the information elements based on the mask image corresponding to the background color values, and updating the color values of the pixel points of the information elements in the matching information image to the background color values to obtain the background image of the matching information image.
As shown in fig. 6, the relationship between the information element group in the information image and the background image is classified into four types, including: 1. directly on the background: without an explicit first-level visual background, the set of information elements is placed directly on the background image; 2. single color: an information element group is placed on a single color area in the background image; 3. low contrast background: the individual information elements of one group of information elements are placed on different image areas of low contrast, e.g. gradient or homogenous color, 4. Mixed color background: each information element in one group of information elements is placed on two image areas with a high contrast. For the first three types, the background image can be determined according to the background color value corresponding to each information element group, but for the fourth type, if the background color value corresponding to each information element group is still used for clustering to generate the background image, pixel points with color filling errors exist in the background image.
Specifically, in the case that each information element in one information element group corresponds to a different background color value, for each information element, the server may extract a color value of any pixel point in the element detection frame of each information element as a background color value of the information element, and then use the background color value of each information element as a clustering seed, and the clustering process and the process of generating the background image may refer to the above step of generating the background image by clustering using the background color value corresponding to each information element group, which is not described herein.
In this embodiment, under the condition that each information element in one information element group corresponds to a different background color value, the background color values in the matching information images are clustered to generate the background image, so that a more accurate background image can be obtained, and the accuracy of generating the background image is improved.

in step 702, a target information image is acquired in response to an image generation instruction.

Step 708, grouping each filling image area in the target transition image to obtain at least one filling image area group, determining element detection frames corresponding to each filling image area in the filling image area group, and forming the information elements to which each determined element detection frame belongs into a target information element group.
And step 710, segmenting element images of information elements in each target information element group from the target information image to obtain a target element image group corresponding to each target information element group.
Step 712 determines, for each candidate information image in the set of candidate information images, a degree of matching of the candidate information image with the at least one target set of element images based on the set of element images of the candidate information image.
Step 714, determining a matching information image from the candidate information image set based on the degree of matching.
Step 716, determining a background image of the matching information image.
Step 718, for each target element image group, merging each element image in the corresponding target element image group into the position of each matching element image group in the background image of the matching information image, thereby obtaining the generated information image.
In the embodiment, at least one target information element group is obtained by detecting and grouping information elements in the target information image, and then element images of the information elements in each target information element group are segmented from the target information image, so that automatic extraction of the information elements in the target information image is realized, and a reusable element image is obtained; by determining the background image of the matched information image and combining each target element image group with the background image, the editable generated information image can be quickly generated, and the efficiency of information image design is improved.
