Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
Fig. 1 is a flowchart of steps of a picture generation method provided in an embodiment of the present invention, which is applied to a terminal, and as shown in fig. 1, the method may include:
In the embodiment of the present invention, the target size may be set according to actual requirements. When the target size ratio is determined, the size ratio of each target size may be determined, and then the size ratios of the target sizes corresponding to the same size ratio may be summarized as one target size ratio. For example, assume that the target dimensions include: 30 × 40, 10 × 10, 60 × 80, 100 × 100, the target sizes correspond to the size ratios: 3:4, 1:1, 3:4, 1: 1. Accordingly, the same size ratio 3:4 corresponding to the target sizes 30 × 40 and 60 × 80 may be determined as one target size ratio, and the same size ratio 1:1 corresponding to the target sizes 10 × 10 and 100 × 100 may be determined as one target size ratio, thereby obtaining two target size ratios.
102, generating a first intermediate graph according with the target size proportion according to the picture to be processed for each target size proportion; the total number of the first intermediate figures is equal to the total number of the target size ratios.
In the embodiment of the invention, the pictures to be processed can be pictures which need to be manufactured into different sizes, and the pictures to be processed can be selected according to actual requirements. Further, in an actual application scenario, since the target size is often a ratio of a mainstream display size or a ratio of a mainstream display scene belonging to the device, for example, 16:9, 1:1, 3:2, 3:4, and so on, that is, a plurality of target sizes are often attributed to several size ratios, the number of target size ratios is often not greater than the number of target sizes. Therefore, in the embodiment of the present invention, a first intermediate map meeting the target size ratio may be generated according to the to-be-processed picture, and for example, if there are 5 target size ratios, 5 first intermediate maps may be generated accordingly. In the subsequent steps, the picture does not need to be respectively cut for each target size, and the picture with the target size can be obtained only by zooming on the first intermediate graph, so that the execution times of cutting are reduced to a certain extent.
103, generating a picture with the size matched with the target size according to the first intermediate graph for each first intermediate graph to obtain a target picture; the total number of the target pictures is larger than the number of the pictures to be processed.
In the embodiment of the present invention, the terminal may adjust the size of the first middle graph by scaling the size of the first middle graph, and specifically, may scale the size of the first middle graph to a target size that meets a target size proportion of the first middle graph, thereby implementing generation of the target picture. Wherein scaling may refer to scaling down or up. Accordingly, in the embodiment of the present invention, if the size of the first intermediate map is larger than the target size, scaling the size of the first intermediate map may specifically be: and reducing the size of the first intermediate image to a target size. If the size of the first intermediate map is smaller than the target size, scaling the size of the first intermediate map may specifically be: the size of the first intermediate image is enlarged to a target size. It should be noted that, if the size of the first intermediate map is equal to the target size, the first intermediate map may be directly used as the target picture.
In summary, in the image generating method provided in the embodiment of the present invention, for at least one specified target size, one or more target size ratios are determined, where one target size ratio corresponds to one or more target sizes, then for each target size ratio, according to the to-be-processed image, a first intermediate image conforming to the target size ratio is generated, and then, according to the first intermediate image, an image with a size matching the target size is generated, so as to obtain a target image; the total number of target pictures is greater than the number of pictures to be processed. Therefore, the first intermediate graph which accords with the proportion of each target size is generated firstly, and the target picture is generated on the basis of the first intermediate graph, so that the target pictures with different target sizes can be obtained by zooming based on the first intermediate graph without performing one-time clipping operation on each target size, the number of times of performing clipping can be reduced to a certain extent, and the picture processing efficiency is improved.
Fig. 2 is a flowchart of steps of another picture generation method provided in an embodiment of the present invention, which is applied to a terminal, and as shown in fig. 2, the method may include:
In this step, the original picture may be a basic picture provided in advance in a preset picture production process. When generating pictures with different target sizes, it is often necessary to acquire related information of an original picture, perform operations such as picture enhancement, picture transcoding, and identification of elements in the original picture on the original picture, and these processes are performed on the basis of the original picture with the same content. Therefore, in the embodiment of the present invention, operations that are repeatedly executed for different target sizes in the image processing flow may be uniformly executed on the original image: the method comprises the steps of picture information obtaining operation, picture enhancing operation, picture transcoding operation and element identification operation, and then a picture to be processed can be obtained.
The operation of obtaining the picture information is also called a picture reverse display operation. The operation may be used to obtain related information of the original picture, for example, to obtain information of the width and height of the original picture, picture quality information, original format, number of original frames of the picture, picture rotation direction, and original data amount, which may be used to guide a subsequent production strategy, that is, used in performing a subsequent operation on the picture.
The picture enhancement operation can be used for enhancing parameters such as brightness, color and definition of the original picture so as to improve the quality of the original picture, further optimize the display effect of a target picture finally generated based on the original picture when the target picture is displayed, and improve the viewing experience of a user.
The image transcoding operation may include one or more of a watermark covering operation, a watermark adding operation, and a format conversion operation, where the watermark removing operation may be used to remove a watermark from an original image to avoid an influence of the watermark on subsequent processing, and the watermark adding operation may be used to add a specified uniform watermark to the original image, where the uniform watermark refers to a watermark that needs to be added to target images of different target sizes. The format conversion operation may be used to convert the picture format of the original picture to a specified base format.
The element recognition operation is also called an intelligent recognition operation, and the operation can be used for recognizing information such as persons, objects, color distribution and the like contained in the picture.
Accordingly, this step may include: executing picture information acquisition operation on the original picture to obtain picture related information of the original picture; the picture related information at least comprises picture quality information; performing a picture enhancement operation on the original picture based on the picture quality information; and performing picture transcoding operation and element identification operation on the original picture after the picture enhancement operation is performed. In the embodiment of the invention, the picture to be processed is obtained by executing the picture information obtaining operation, the picture enhancing operation, the picture transcoding operation and the element identification operation, the quality of the picture to be processed can be improved to a certain extent, the picture to be processed is obtained by only executing the operations once on the original picture, the target pictures with different target sizes can be generated by carrying out subsequent operations on the basis of the picture to be processed, and the processing resources required by picture processing can be further reduced to a certain extent.
Specifically, when the image information obtaining operation is executed, the original image may be subjected to image analysis, and then the related information may be obtained from the analyzed image. Accordingly, the obtained related information can be cached for use in the subsequent steps.
Further, when performing a picture enhancement operation, picture quality information may be obtained from the cached information, and the picture quality information may be parameters capable of representing the current image quality of the original picture, such as the brightness, the sharpness, and the like of the picture.
Then, the current picture quality information and the original picture can be used as the input of a preset image enhancement model, and the original picture is enhanced through the preset image enhancement model.
Further, when the watermark removing operation is performed, image recognition may be performed on the enhanced picture, that is, the original picture after the picture enhancing operation is performed, to determine the watermark included in the original picture and the position of the watermark, and then the watermark at the position may be deleted. When the watermark adding operation is executed, the watermark to be added can be added at the designated position, and when the format conversion operation is executed, the original picture can be used as the input of a preset format conversion algorithm, and the original picture is converted into the designated format through the preset format conversion algorithm. When the element identification operation is performed, element detection may be performed on the original picture after the picture enhancement operation is performed by using a preset detection algorithm, and then the distribution position of each element included in the original picture in the picture is determined.
For at least one of the target sizes specified, one or more target size ratios are determined, one target size ratio corresponding to the one or more target sizes, step 202.
And 203, generating a first intermediate graph according with the target size proportion according to the picture to be processed for each target size proportion.
It should be noted that, for implementation of each step in the embodiment of the present invention, reference may be made to relevant descriptions in other embodiments, and details are not described here again.
According to the picture generation method provided by the embodiment of the invention, a picture to be processed is obtained by sequentially executing picture information acquisition operation, picture enhancement operation, element identification operation and picture transcoding operation on an original picture; for at least one specified target size, determining one or more target size proportions, wherein one target size proportion corresponds to one or more target sizes, then generating a first intermediate graph conforming to the target size proportion according to the picture to be processed for each target size proportion, and then generating a picture with the size matched with the target size according to the first intermediate graph to obtain a target picture; the total number of target pictures is greater than the number of pictures to be processed. In this way, by first extracting and executing operations that are repeatedly executed for different target sizes in the picture processing flow: the method comprises the steps of obtaining picture information, enhancing pictures, transcoding pictures and identifying elements, unnecessary repeated execution can be avoided to a certain extent, processing resources consumed by picture generation are reduced, meanwhile, first intermediate pictures which accord with all target size proportions are generated firstly, and target pictures are generated on the basis of the first intermediate pictures, so that cutting operation is not required to be executed once for each target size, target pictures of different target sizes can be obtained by zooming based on the first intermediate pictures, the number of times of execution of cutting can be reduced to a certain extent, and the picture processing efficiency is improved.
Fig. 3 is a flowchart of steps of another image generating method provided in an embodiment of the present invention, which is applied to a terminal, and as shown in fig. 3, the method may include:
And 303, for each target size ratio, cutting the to-be-processed picture into a picture which meets the target size ratio and has the largest size according to the original size acquired by the picture information acquisition operation and the element distribution identified by the element identification operation, so as to obtain the first intermediate picture.
In an actual application scenario, the size of a target picture that needs to be generated finally, that is, the target size is often different from the size of an original picture, that is, the size of a picture to be processed. Thus, it is often necessary to perform a cropping operation for each target size. Therefore, in this step, the to-be-processed picture can be cut into the picture with the largest size and the target size ratio, so as to obtain the first intermediate map. Therefore, in the subsequent steps, the cutting is not needed, and the target pictures with different target sizes under the target size proportion corresponding to the first intermediate picture can be obtained only by scaling the first intermediate picture according to the different target sizes under the target size proportion corresponding to the first intermediate picture, so that the cutting times are reduced to a certain extent, and the resources consumed by the cutting operation are reduced.
Specifically, in the embodiment of the present invention, the target size ratio may be determined according to the at least one target size specified in step 302, and then the clipping may be performed according to the target size ratio. Wherein each target size ratio corresponds to a clipping operation. For example, assume that 11 target sizes are included: 100 x 100, 200 x 200, 300 x 300, 300 x 200, 600 x 400, 1200 x 800, 1600 x 900, 3200 x 1800, 300 x 400, 600 x 800, 1200 x 1600. If clipping is done directly, 11 clipping operations need to be performed. In the embodiment of the present invention, 4 target size ratios can be determined according to the 11 target sizes: 1:1, 3:2, 16:9, 1: 1. Accordingly, only 4 cropping needs to be performed to obtain a first intermediate map with a scale of 1:1, a first intermediate map with a scale of 3:2, a first intermediate map with a scale of 16:9, and a first intermediate map with a scale of 3: 4. Subsequently, the first intermediate graph with the comparison ratio of 1:1 is scaled according to the target size meeting 1:1, and the size is obtained as follows: the three pictures, 100 x 100, 200 x 200, 300 x 300, were scaled according to the target size according to 3:2 by the first intermediate graph of comparative example 3:2, to obtain the dimensions: the three pictures 300 x 200, 600 x 400, 1200 x 800 were scaled according to the target size of 16:9 by the first intermediate graph of comparative example 16:9, resulting in the sizes: 1600 x 900, 3200 x 1800, scaled by the target size according to 3:4 by the first middle graph of comparative example 3:4, the size is obtained as: 300 x 400, 600 x 800, 1200 x 1600.
Further, according to the original size obtained by the picture information obtaining operation and the element distribution identified by the element identifying operation, when clipping is performed, the maximum size which can be reserved under the condition of meeting the target size proportion can be determined according to the original size, and according to the element distribution, the optimal clipping position which can cause the minimum damage to important elements under the condition of meeting the target size proportion and being reserved to the maximum size is determined. Finally, the clipping can be performed according to the maximum size and the optimal clipping position. When determining the optimal cropping position, important elements may be determined from the identified elements, for example, a person element may be determined as an important element, or an element with the largest area may be determined as an important element. Then, the damage degree of the important element at each clipping position can be determined, and the clipping position with the minimum damage degree is determined as the optimal clipping position. Wherein, the smaller the remaining area of the important element after clipping from the clipping position, the greater the destruction degree corresponding to the clipping position.
For example, assuming a target size ratio of 1:1, the size of the picture to be processed is 2150 × 2050, and the maximum size that can be retained is 2050 × 2050. Further, assuming that the important element in the to-be-processed picture is determined to be a character element, and the damage degree to the important element at different cropping positions is determined, when the position of the 100 th element on the left side is vertically cropped, the damage to the character element is the minimum, then the position of the 100 th element on the left side can be vertically cropped, and the first intermediate picture which meets the target size ratio and has the largest size is obtained.
In the embodiment of the invention, the first intermediate graph is maximized during clipping, so that when the first intermediate graph is zoomed to generate the pictures with the target sizes on the basis of the first intermediate graph, the problem of poor definition of the pictures obtained after zooming due to small size of the first intermediate graph can be avoided to the greatest extent, and the quality of the generated pictures can be further ensured to a certain extent.
It should be noted that, for implementation of each step in the embodiment of the present invention, reference may be made to relevant descriptions in other embodiments, and details are not described here again.
In summary, the image generating method provided in the embodiment of the present invention may first extract and execute operations that are repeatedly executed in the image processing flow for different target sizes: the method comprises the steps of obtaining picture information, enhancing pictures, transcoding pictures and identifying elements, avoiding unnecessary repeated execution to a certain extent, further reducing processing resources consumed by picture generation, simultaneously generating a first intermediate picture which accords with each target size proportion and has the largest size by first generation, and generating target pictures on the basis of the first intermediate picture, so that cutting operation is not required to be executed for each target size, the target pictures with different target sizes can be obtained by scaling based on the first intermediate picture, further reducing the execution times of cutting to a certain extent, improving the picture processing efficiency, and avoiding the problem of poor definition of the pictures obtained after scaling due to the fact that the size of the first intermediate picture is small to the greatest extent, and further ensuring the quality of the generated pictures to a certain extent.
Fig. 4 is a flowchart of steps of another image generating method provided in an embodiment of the present invention, which is applied to a terminal, and as shown in fig. 4, the method may include:
The implementation manner of each step in the embodiments of the present invention may refer to the related description in other embodiments, and is not described herein again.
And step 404, for each first intermediate graph, according to the picture related information obtained by the picture information obtaining operation, performing transcoding operation meeting the personalized transcoding requirement corresponding to the target size on the first intermediate graph to obtain a second intermediate graph.
In this step, the picture related information may include at least one of an original data size, an original format, a picture original frame number, and a picture rotation direction, and accordingly, at least one of the following operations may be performed on the first intermediate map:
operation A: and compressing the data size of the first intermediate graph to a target size according to the original data size.
Specifically, when the data size of the first intermediate map is compressed to the target size according to the original data size, the difference between the original data size and the target size may be determined first, and then the compression mode may be selected according to the difference. Finally, the first intermediate graph can be compressed based on the compression mode.
And operation B: adding a target watermark to the first intermediate map.
Further, when adding the target watermark to the first intermediate map, the watermark to be added, which is set in advance for the target size ratio corresponding to the first intermediate map, may be obtained first, and then the watermark to be added is added to the preset position. Wherein, one target size ratio may correspond to a plurality of watermarks to be added, and for example, it is assumed that for the target size ratio: 1:1 sets 3 to-be-added watermarks, then 3 first intermediate graphs can be copied to obtain 3 first intermediate graphs, and then the 3 first intermediate graphs are respectively added with a watermark a, a watermark b and a watermark c.
And operation C: and converting the format of the first intermediate graph into a target format according to the original format.
According to the original format, when the format of the first intermediate graph is converted into the target format, a format conversion mode can be selected according to the original format and the target format, and finally, the format of the first intermediate graph is converted based on the format conversion mode. The target format can be various formats such as jpg, png, gif, webp, bpg and the like.
Operation D: and adjusting the frame number of the first intermediate image to be a target frame number according to the original frame number of the image.
When the frame number of the first intermediate map is adjusted to the target frame number according to the original frame number of the picture, a difference between the original frame number of the picture and the target frame number may be determined, and then frame extraction or frame addition may be performed on the first intermediate map according to the difference, so that the frame number of the first intermediate map reaches the target frame number.
Operation E: and adjusting the direction of the first intermediate map to be a target direction according to the picture rotation direction.
When the direction of the first intermediate map is adjusted to the target direction according to the picture rotation direction, a rotation mode may be determined according to the picture rotation direction and the target direction, and then the picture may be rotated according to the rotation mode so that the direction of the first intermediate map is changed to the target direction.
The target size, the target watermark, the target format, the target frame number and the target direction all meet the individual transcoding requirements, different individual transcoding requirements can be determined according to requirements, and the individual transcoding requirements corresponding to different target sizes may be different. For example, the target direction may be rotated by 90 ° when generating a target picture of a target size 100 × 100, and may be rotated by 270 ° when generating a target picture of a target size 300 × 300.
Further, these operations may be performed in an overlapping manner, that is, after one operation is performed, the next operation is performed continuously on the operation performing result, for example, the watermarking may be performed first, the intermediate map a is produced, format conversion is performed on the basis of the intermediate map a, the intermediate map b conforming to the target format is produced, and then scaling is performed on the basis of these b through subsequent steps. Of course, the operations described above may also be executed independently, and the embodiment of the present invention is not limited thereto. In this way, the transcoding operation meeting the personalized transcoding requirement corresponding to the target size can be executed on the first intermediate by executing the operations.
And 405, scaling the size of the second intermediate image to the target size to obtain the target image.
It should be noted that, since the second intermediate map obtained in the embodiment of the present invention is a picture which meets the target size scale and has the largest size, in this case, the operation of scaling the size of the second intermediate map to the target size may specifically be: and reducing the size of the second intermediate image to the target size. For example, assuming that the size of the second middle graph is 2050 × 2050, the second middle graph may be reduced to obtain a 100 × 100 target graph, a 200 × 200 target graph, and a 300 × 300 target graph in a 1:1 ratio.
In the embodiment of the invention, the transcoding operation meeting the personalized transcoding requirement corresponding to the target size is performed on the first intermediate image to obtain the second intermediate image, and the second intermediate image is zoomed to obtain the target image with the size meeting the requirement and the image effect meeting the requirement, so that the image effect of the target image can be improved.
It should be noted that, in the embodiment of the present invention, the terminal may cache the pictures or information obtained after each operation is performed, so as to facilitate use in the subsequent step. Further, the terminal can also send the finally obtained target picture to a preset server, and accordingly, the server can store the received target picture so as to facilitate display of other equipment. The server may be a Content Delivery Network (CDN) server.
Furthermore, in the embodiment of the present invention, each step is executed by a terminal, so that data transmission among the steps is transmitted among each component inside the terminal, and thus, the cost of network IO can be saved to a certain extent. Of course, each step in the image generation method provided in the embodiment of the present invention may also be performed in the cloud, that is, executed by the server. Accordingly, each step may be implemented by one cloud service call, and the picture generation method is implemented by multiple service calls, which is not limited in the embodiment of the present invention.
In summary, the image generating method provided in the embodiment of the present invention may first extract and execute operations that are repeatedly executed in the image processing flow for different target sizes: the method comprises the steps of obtaining picture information, enhancing pictures, transcoding pictures and identifying elements, avoiding unnecessary repeated execution to a certain extent, further reducing processing resources consumed by picture generation, simultaneously generating a first intermediate picture which accords with each target size proportion and has the largest size by first generation, and generating target pictures on the basis of the first intermediate picture, so that cutting operation is not required to be executed for each target size, the target pictures with different target sizes can be obtained by scaling based on the first intermediate picture, further reducing the execution times of cutting to a certain extent, improving the picture processing efficiency, and avoiding the problem of poor definition of the pictures obtained after scaling due to the fact that the size of the first intermediate picture is small to the greatest extent, and further ensuring the quality of the generated pictures to a certain extent.
Fig. 5 is a schematic diagram of generating a picture according to a specific example provided in an embodiment of the present invention, and as shown in fig. 5, the embodiment of the present invention may implement picture production by performing the following operations:

The operation graph of each size under each proportion is a target picture of different target sizes under the target size proportion.
And operation 3, distributing the operation graphs of all sizes under all proportions.
Specifically, the operation diagram may be sent to a server, and accordingly, the server may store the received operation diagram to facilitate the acquisition and display of other devices. When the operation diagrams are transmitted to the servers, all the operation diagrams may be transmitted to each server, or the operation diagrams at each ratio may be transmitted to the servers corresponding to the ratio.
For example, fig. 6 shows another schematic diagram of picture generation, as shown in fig. 6, when an operation diagram with a size of 1080 × 608 is generated, it is necessary to perform one-pass operations of picture reverse rendering, picture enhancement, intelligent recognition and transcoding on an original picture, and when an operation diagram of 600 × 600 is generated, it is also necessary to perform one-pass operations of picture reverse rendering, picture enhancement, intelligent recognition and transcoding on an original picture. That is, when generating a plurality of target sizes, the process flow needs to be executed a plurality of times. It should be noted that the production transcoding and the bulk transcoding in fig. 5 may be equivalent to the transcoding in fig. 6, and the production transcoding and the bulk transcoding may be performed by calling two services.
In the embodiment of the invention, when the operation graphs of different proportions and sizes are generated, only one time of picture reverse display, picture enhancement, intelligent identification and transcoding manufacture is needed, and then batch transcoding is carried out on the obtained first intermediate graphs of the proportions, so that the operation graphs of the sizes, namely the target pictures, can be obtained. Therefore, when the pictures with various target sizes are generated, the required resource consumption can be reduced to a certain extent through multiplexing part of operations, and the generation efficiency is further improved.
