When the terminal apparatuses 101, 102, 103 are hardware, various electronic apparatuses are possible, and when the terminal apparatuses 101, 102, 103 are software, the electronic apparatuses may be installed therein. Which may be implemented as multiple software or software modules (e.g., multiple software modules for providing distributed services), or as a single software or software module.

It should be understood that the number of terminal devices, networks and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to fig. 2, a flow 200 of one embodiment of a method for determining a picture format according to the present disclosure is shown. The method for determining the picture format comprises the following steps:
step 201, performance preference information of a user on picture performance is obtained, wherein the performance preference information comprises at least one performance preference and a preset weight corresponding to the performance preference.
In this embodiment, an execution subject (e.g., a server shown in fig. 1) of the method for determining a picture format may acquire performance preference information of a user for picture performance from a user terminal. The performance preference information includes performance preferences and preset weights corresponding thereto. The picture performance refers to The effect of different formats of pictures on The performance of The hardware or software applied to The pictures under different hardware or software environments, for example, the parsing capability of The JPEG (Joint Photographic Experts Group ) format under The ARM (Advanced RISC Machines, advanced reduced instruction set processor) architecture, the color support of The PNG (Portable Network Graphic, portable network graphics) format under The X86 architecture, the storage data amount of The SVG (Scalable Vector Graphics ) format picture in The Windows system, and The like. The performance preference and the preset weight corresponding to the performance preference can represent the preference and the preference degree of the user on the format performance, for example, the user has three performance preferences on the picture format, one is that the picture corresponding to the picture format is applied to the program under the ARM architecture, and the weight corresponding to the performance preference is 0.7; secondly, the storage amount of the picture corresponding to the picture format is small, and the weight corresponding to the performance preference is 0.2; thirdly, the pictures corresponding to the picture formats are simultaneously applied to the program under the X86 architecture, and the weight corresponding to the performance preference is 0.1. It will be appreciated that a greater weight for a performance preference indicates a greater degree of preference by the user for that performance preference.
Step 202, for each of the different picture formats, determining a format performance matching the picture format with the performance preference according to the performance preference, determining a performance index value of the format performance, and determining a performance score of the picture format according to the performance index value of the format performance and a preset weight corresponding to the performance preference.
In this embodiment, for each of the picture formats, or for each of several picture formats selected by the user, according to the performance preference, each format performance of the picture format is matched with each performance preference in the performance preference information, and then, according to the performance index value of each format performance and the preset weight corresponding to the performance preference matched with each format performance, the performance score of the picture format is determined.
For example, the performance preferences of the user are: the picture is applied to ARM architecture, X86 architecture, has requirements on the size of the picture, has requirements on the color support of the picture, and the preset weights corresponding to the performance preferences are as follows: ARM architecture weight 0.9, X86 architecture weight 0.8, picture size weight 0.8, color weight 0.2. The knowledge base may be obtained through user input, internet queries, or server local storage: the performance index value of the analysis capability of the PNG format under the ARM architecture is 70 points, the performance index value of the analysis capability under the X86 architecture is 60 points, the performance index value of the picture size is 75 points, and the performance index value of the color support degree is 30 points; the SVG format has a performance index value of 80 for the resolution capability under ARM architecture, a performance index value of 90 for the resolution capability under X86 architecture, a performance index value of 85 for the picture size, and a performance index value of 70 for the color support. Then, the PNG format final score may be determined as: (70×0.9+60×0.8+75×0.8+30×0.2)/4=44.25; the SVG format final score is: (80×0.9+90×0.8+85×0.8+70×0.2)/4=56.5.
For another example, according to the size of the weight, the performance index value of the format performance corresponding to the performance preference with the largest weight may be selected as the performance score of the picture format, in the above example, if the weight of the ARM architecture is the largest, the performance index value of the resolution capability under the ARM architecture corresponding to the ARM architecture is selected as the performance score of the picture format, and at this time, the PNG format final score is 70 points, and the SVG format final score is 80 points.
In step 203, the target picture format is determined from the different picture formats according to the performance scores of the different picture formats.
In this embodiment, the target picture format is determined from the picture formats according to the performance scores of the picture formats. Each picture format may be arranged according to its performance score, and a pre-set number of picture formats with the highest performance score may be selected as the target picture format.
According to the method for determining the picture format, the performance scores of different picture formats are determined according to the user requirements, and the target picture format is determined according to the performance scores, so that accuracy in determining the picture format can be improved.
Optionally, determining the target picture format from the different picture formats according to the performance scores of the different picture formats includes: and determining the picture format with the performance score reaching a preset score threshold value from the performance scores of different picture formats as a target picture format.
In this embodiment, a score threshold for filtering the picture formats may be preset, and after determining the performance score of each picture format, the picture format with the performance score reaching the score threshold is used as the target picture format. The target picture format is screened by presetting the score threshold, so that the screening step can be simplified, and the screening efficiency is improved.
With further reference to fig. 3, a flow 300 of another embodiment of a method for determining a picture format is shown, comprising the steps of:
step 301, performance preference information of a user on picture performance is obtained, wherein the performance preference information comprises at least one performance preference and a preset weight corresponding to the performance preference.
Step 302, for each of the different picture formats, determining a format performance matching the picture format with the performance preference according to the performance preference, determining a performance index value of the format performance, and determining a performance score of the picture format according to the performance index value of the format performance and a preset weight corresponding to the performance preference.
Step 303, determining a target picture format from different picture formats according to the performance scores of the different picture formats.
In this embodiment, descriptions of step 301, step 302, and step 303 are identical to those of step 201, step 202, and step 203, and will not be repeated here.
Step 304, taking the picture with the picture format being the target picture format in the preset picture library as the target picture.
In this embodiment, a picture library including candidate pictures may be obtained through user input, internet, or local storage, where the candidate pictures in the picture library are in different picture formats. And after determining the target picture format, taking the candidate picture with the picture format being the target picture format in the picture library as the target picture. It will be appreciated that the target picture may be as material for program development, data for a test system, or a sample of a trained neural network model, etc.
Step 305, optimizing the picture performance of the target picture according to the performance preference information.
In this embodiment, the image processing method may be used to further optimize the image performance of the screened target image according to the performance preference information of the user. For example, if the performance preference information includes a high compression ratio requirement on the picture, image compression processing may be performed on the target picture; the performance preference information includes sensitivity to the color of the picture, and then the target picture can be subjected to color reconstruction, picture color contrast is increased, and the like.
According to the embodiment, the target picture is determined according to the target picture format, and the target picture is subjected to performance optimization according to the performance preference information of the picture, so that the target picture can further meet the requirement of a user on the picture performance, and the convenience and satisfaction of the user are improved.
Optionally, optimizing the picture performance of the target picture according to the performance preference information includes: according to the performance preference information, at least one of the following processes is carried out on the target picture: compression processing, color reconstruction, elimination or generation of a transparent channel of a target picture, recoding, extraction and optimization of key features of the target picture.
In this embodiment, performance optimization operations may be performed on the target picture according to the performance preference information, where the performance optimization operations may be one or more of the following picture processing operations: a picture compression process of compressing the size of an original picture, for example, by re-encoding a binary-encoded picture, or compressing the size of a picture by reducing the resolution of the picture, etc.; picture color reconstruction, for example, enhancing the contrast of the picture color by enhancing the color contrast, or converting the picture in RGB565 color mode into the picture in RGB888 color mode by a color mode conversion method, improving the richness of the picture color, etc., wherein the RGB color mode is a color standard in the industry, and is to obtain various colors by the variation of three color channels of red (R), green (G) and blue (B) and the superposition of the three color channels; a process of eliminating or generating a picture transparent channel, for example, creating a transparent channel (i.e., an alpha channel) of a picture using a picture transparent channel generation method, or closing a transparent channel of a picture using a picture transparent channel elimination method; re-encoding of picture data, e.g. lossy re-encoding binary data of the generated picture, i.e. for parts of the image that are insensitive to certain data/encoding fields, allows these insensitive parts to be lost during picture compression in exchange for the maximum compression ratio; and extracting key features, namely key information, in the picture by using a picture feature extraction method, and then performing performance optimization on picture data/codes corresponding to the key information.
According to the embodiment, the performance of the target picture is optimized according to the performance preference information of the picture, so that the performance of the target picture can be further improved, and the requirement of a user on the performance of the picture is further met.
In some alternative implementations of the embodiments described above in connection with fig. 2 and 3, the format performance includes an effect of the picture format on the performance of the preset program in the preset application environment or the preset development environment.
In the present embodiment, the format performance of a picture refers to the influence of a picture format in a certain application environment or a certain development environment on the performance of a program/hardware in the application environment or the development environment. For example, when a picture in a certain picture format is applied to a program in the ARM architecture, the program can analyze the picture in the certain picture format at a resolution speed, a resolution accuracy, or the like (i.e., the resolution of the picture format in the environment of the ARM architecture), or when a picture in the certain picture format is applied to software in the Windows operating system, color fidelity or the like when the picture in the certain picture format is displayed by the software.
