As shown in fig. 1, the jigsaw method provided in the embodiment of the present application includes:
and step S101, acquiring image characteristic information of all material images in at least one material atlas.
In application, at least one material image set for jigsaw puzzle can be stored in advance in a storage medium of the terminal equipment, and each material image set can only comprise material images of the same type. In step S101, image feature information of all material images in at least one material atlas selected by the user may be acquired according to actual needs of the user. The image characteristic information may include a size and a color value of the material image.
In one embodiment, step S101 includes:

In one embodiment, before step S101, the method includes:
and when detecting the starting operation of the user on the jigsaw of the target image, entering a jigsaw interface of the target image.
In an application, the target image may be an image displayed in a desktop interface of the terminal device, an image preview interface of an album, an arbitrary folder interface, or a jigsaw puzzle picture making software (e.g., montage picture making software) interface. The starting operation of the jigsaw puzzle can be any triggering operation of the target image or an interface for displaying the target image, and can be set according to actual needs. For example, a tile start button or icon may be provided in an interface displaying the target image, and the tile start operation may be any touch operation such as clicking, pressing, or touching the tile start button or icon. The tile launch operation may also be a voice control operation or a gesture control operation.
As shown in fig. 2, an image preview interface 1 is exemplarily shown, and a target image 11 and a tile starting button 12 are displayed in the image preview interface 1.
In one embodiment, step S101 includes:
when the triggering operation of a user on an atlas selection area displayed by the jigsaw interface is detected, entering the atlas selection interface;
and when the selection operation of the user on at least one material atlas displayed on the atlas selection interface is detected, acquiring the image characteristic information of all material images in the at least one material atlas selected by the user.
In an application, the atlas selection area may be an atlas selection button or icon, and the trigger operation may be any touch operation such as clicking, pressing or touching the atlas selection button or icon. The selection operation can be any touch operation such as clicking, pressing or touching a selection frame in any material atlas in at least one material atlas displayed on the atlas selection interface. The trigger operation or selection operation may also be a voice control operation or a gesture control operation.
In application, after a user finishes selecting the material atlas, thumbnails of all the material atlases selected by the user are displayed in a jigsaw interface according to the selection sequence of the user, the user can continue to select other material atlases and can also cancel the selection of the selected material atlases, and the thumbnail of each material atlas is used for displaying part of material images in the material atlas.
In the application, a user can select a material atlas according to a self-defined priority order, a system (namely, a computer program or an operating system for executing the jigsaw method) can default that the priority of the material atlas selected by the user firstly is higher than that of the material atlas selected later, and in the subsequent jigsaw process, the system can screen out material images which can be used for jigsaw puzzle from the material atlas with the higher priority according to the priority order.
As shown in fig. 3, a diagram illustrating an atlas selection process is exemplary. An album selection area 31 is shown in the exemplary tile interface 3 in figure 3; a plurality of material atlases (six selectable material atlases are shown in an exemplary illustration in fig. 3 and respectively represented as a material atlas I, a material atlas II, a material atlas III, a material atlas IV, a material atlas V and a material atlas six) are displayed in the atlas selection interface 32, and a selection frame (an exemplary illustration in fig. 3 is a distance frame) is displayed in each material atlas; after the user completes the material atlas selection operation, thumbnails of all the material atlases selected by the user (two material atlases are exemplarily shown in fig. 3, and three material images in the material atlas, which are respectively represented as a material image one, a material image two, and a material image three, are indicated in the thumbnail of each material atlas) and the atlas selection area 31 are displayed in the puzzle interface 3 in the order selected by the user.
As shown in fig. 4, in one embodiment, before step S101, the method includes:
step S401, performing image recognition on material images to be classified, and dividing the material images containing the same elements into the same type;
and S402, generating at least one material atlas, and adding material images of the same type into the same material atlas.
In application, in order to facilitate a user to select a required material atlas, the material images need to be classified in advance, the material images containing different elements are divided into different types, the material images of the same type are added into the same material atlas, and the user can name each material atlas. The elements in the material image may be a human face or an object, and the material image may also include a specific scene composed of a plurality of elements.
As shown in fig. 5, in one embodiment, step S401 includes:
step S501, when the template material image selection operation of a user is detected, acquiring a material image selected by the user as a template material image;
step S502, carrying out image recognition on the template material image, and acquiring elements in the template material image as target elements;
and S503, carrying out image recognition on the material images to be classified according to the target elements, and dividing the material images containing the target elements into the same type.
In application, when a user needs to screen a material image containing a certain specific element from material images to be classified and add the material image into the same material image set, one material image containing the specific element can be selected as a template material image, so that the system can automatically identify the specific element in the template material image, and then identify other material images containing the specific element from a plurality of material images to be classified.
In application, the material image selected by the user in step S501 may be one of the material images to be classified or classified, and the template material image selection operation may be any trigger operation on the material image selected by the user. In step S502 and step S503, according to the difference of the element types in the template material image, a corresponding image recognition algorithm may be used for image recognition, for example, when the element is a face, a face recognition algorithm may be used; when the element is an article, an article identification algorithm can be adopted; when the material image includes a specific scene, a scene recognition algorithm may be employed.
In application, a user can sequentially select material images containing different elements or scenes as template material images, so that the system can sequentially generate different material atlases according to the template material images. The user can also select a plurality of material images containing different elements or scenes at one time as template material images, so that the system can quickly generate a plurality of different material atlases according to all the template material images at one time.
Step S102, dividing the target image into a preset number of sub-image areas corresponding to the width of a preset color gamut range, and generating jigsaw feature information of the target image.
In application, the preset color gamut range may be set by a user in a self-defined manner in advance, and if the user is not set in advance, a default color gamut range of the system or a color gamut range set by the user last time is adopted. The width of the preset color gamut range is inversely related to the number of sub-image areas and the number of material images required for forming the target image by splicing. The wider the preset color gamut, the less color gradation is required, the fewer the number of sub-image regions and the number of required material images, and vice versa.
In application, a user may custom adjust the preset color gamut range according to the number of the material images, for example, if the preset color gamut range set by the user at first is such that the target image is divided into a first number (e.g., 80 × 60) of sub-image regions, a first number of material images are correspondingly required; if the number of the material images in the material atlas selected by the user is insufficient, the user can adjust the preset color gamut range to make the preset color gamut range wider, so that the target image is divided into a second number (for example, 40 × 30) of sub-image regions, and a second number of material images are correspondingly needed; if the number of material images in the material atlas selected by the user is still insufficient, the user may continue to adjust the preset color gamut range until the number of material images in the material atlas selected by the user is sufficient. Under the condition that the number of the material images in the material atlas selected by the user is insufficient and the preset color gamut range is not adjusted by the user, the system can also default to adopt a mode of multiplexing the material images to complete jigsaw puzzle, and the same material image is arranged in at least two sub-image areas according to actual needs to be reused.
In application, the puzzle interface displays a color gamut range setting area, which may be a color gamut range input box, a color gamut range adjustment progress bar, a color gamut range selection button, or an icon.
In application, the jigsaw feature information includes the number of the sub-image areas and the size and the color value of each sub-image area, and when a jigsaw is performed, a material image matched with the size and the color value of the sub-image area needs to be correspondingly set in one sub-image area.
And S103, screening out material images with image characteristic information matched with the jigsaw feature information from the at least one material atlas according to the jigsaw feature information and the image characteristic information, and taking the material images as selected material images.
In application, the material atlas may be a material atlas selected by a user or a material atlas selected by the system by default. The size and color value of the material image in the material image set do not necessarily conform to the size and color value of the sub-image area, and therefore the material image with the image characteristic information matched with the jigsaw feature information needs to be screened out and used as the selected material image for jigsaw puzzle.
And step S104, splicing the selected material images to form a splicing effect image of the target image.
In application, the splicing effect map is an image which is formed by splicing a plurality of selected material images and is identical to the picture of the target image.
As shown in fig. 6, in one embodiment, step S103 includes:
s601, according to the color value of each sub-image area, screening a material image matched with the color value of each sub-image area from the at least one material atlas to serve as a selected material image, wherein one sub-image corresponds to one selected material image;
step S104 includes:
step S602, according to the size of each sub-image area, cutting or amplifying the selected material image corresponding to each sub-image area, so that the size of each sub-image area is the same as that of the corresponding selected material image;
step S603, according to the position of each sub-image area, placing the selected material image corresponding to each sub-image area at the corresponding position in the target image, and splicing to form a splicing effect graph of the target image.
In application, in step S601, color value matching means that color values are the same or belong to the same color gamut; in step S602, when the size of the sub-image region is different from that of the selected material image corresponding thereto, the selected material image corresponding thereto needs to be cut or enlarged to have the same size. The cropping mode may be centered cropping or cropping centered on the position of the target element in the selected material image, so that the cropped selected material image contains the target element and has the same size as the sub-image region.
As shown in fig. 7, in one embodiment, after step S103, the method includes:
s701, displaying jigsaw information of the target image on a jigsaw interface; the mosaic information comprises at least one material image set forming the mosaic effect image and the proportion of selected material images in each material image set in the mosaic effect image.
In application, after the splicing effect graph of the target image is formed by splicing, the splicing information of the target image is displayed on a splicing interface, and the splicing information can comprise at least one material atlas for forming the splicing effect graph and the proportion of the selected material image in each material atlas in the splicing effect graph, and can also comprise a thumbnail of the splicing effect graph and a thumbnail of the target image.
As shown in fig. 8, the exemplary illustration mosaic interface 3 displays an album selection area 31, thumbnails 33 of the mosaic effect map, material albums constituting the mosaic effect map (two material albums are exemplarily shown in fig. 3, and three selected material images in the material album are schematically shown in the thumbnail of each material album, and are respectively represented as a selected material image one, a selected material image two, and a selected material image three), and the proportions of the selected material images in each material album in the mosaic effect map (two material albums are exemplarily shown as a proportion one and a proportion two, respectively in fig. 3).
As shown in fig. 9, in one embodiment, after step S701, the method includes:
step 901, when the sum of the occupation ratios of the selected material images in each material image set in the splicing effect image is less than 1, prompting a user to change the preset color gamut range or increase the material images;
step S902, when detecting the color gamut range changing operation of the user, dividing the target image into a preset number of sub-image areas corresponding to the width of the changed preset color gamut range, and regenerating jigsaw feature information of the target image;
step S903, when the material image adding operation of the user is detected, identifying whether the type of the image added by the user belongs to the type of the material image in at least one material atlas selected by the user, and prompting an identification result; the material image adding operation comprises an image shooting operation or an image importing operation;
step S904, when the type of the image added by the user belongs to the type of the material image in at least one material image set selected by the user, prompting the user whether to take the added image as a new material image;
step S905, when the triggering operation that the user takes the added image as a new material image is detected, updating the splicing effect image and the jigsaw information according to the new material image.
In application, in step S901, when the number of material images in at least one material image set selected by the user is less than the number of sub-image areas in the target image, the splicing effect image is an unfinished semi-finished product, the sum of the occupation ratios of the selected material images in the splicing effect image is less than 1, the system can display the thumbnails of the unfinished splicing effect images on the splicing interface, at this time, the system prompts the user to change the preset color gamut range, and the user can adjust the preset color gamut range to a wider range or add material images. In step S902, after the user changes the preset color gamut range, the system re-executes steps S102 to S104 and S701 according to the changed preset color gamut range. In step S903, when the user starts the camera application to perform an image capturing operation to capture an image, or performs an image importing operation to import an image through wireless (e.g., WiFi or bluetooth) or wired (e.g., USB interface) communication, the system may automatically identify the types of elements in the image added by the user using an image recognition algorithm, and then prompt the user for a recognition result. In step S905, when the user uses the added image as a new material image, the new material image is added to the corresponding material atlas according to the type of the new material image, and steps S103, S104, and S701 are executed again to update the mosaic effect map and the mosaic information according to the new material image.

In step S1002, after detecting a trigger operation of pulling up the photographing region by the user, the system starts a camera application and enters a camera preview interface. In step S1003, the system will automatically recognize the type of the element in the image added by the user by using an image recognition algorithm, and then prompt the user to recognize the result.
