It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, apparatus, article, or device that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or device.

The terminal can be a hardware device with various operating systems, such as a smart phone, a desktop computer, a tablet computer, a notebook computer and the like. The server may comprise a single independently operating server, or a distributed server, or a server cluster consisting of a plurality of servers.
It is noted that the present specification provides method operational steps as described in the examples or flowcharts, but may include more or fewer operational steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one way of performing the order of steps and does not represent a unique order of execution. In actual system or product execution, the methods illustrated in the embodiments or figures may be performed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment). As shown in fig. 1, the method may include the steps of:
S110: and acquiring the original picture and the picture target size.
In the embodiment of the present invention, the target size of the picture is the size of the picture required for displaying, and the original picture may include a local picture specified by the user, a picture downloaded from a network, or a picture obtained synchronously (transmitted through a wired or wireless connection manner) from other electronic devices.
In practical application, the display picture generation method can be applied to various resource management platforms with a picture display function, such as a picture resource aggregation platform, a report resource management platform and the like. The picture target size may also be different due to the different resource management platforms. Because the area of the resource management platform displaying the picture is generally a fixed size and a fixed proportion (for example, 4:3), and the original picture can include various sizes and proportions (for example, 4:3-16:9, >16:9, and unresolved proportions), the original picture needs to be processed to obtain a display picture with the same size and the same proportion as those of the picture required for display, and then the display picture is displayed.
In one possible embodiment, after the obtaining the original picture and the target size of the picture, the method may further include:
Extracting size information of the original picture;
and when the size information accords with a picture filling condition, executing the step of determining the region to be filled of the display picture corresponding to the original picture according to the original picture and the picture target size.
Specifically, the picture filling condition may include that the picture proportion is within a preset proportion range (for example, 4:3-16:9 and 16:9), after the size information of the original picture is extracted, the picture proportion of the original picture may be calculated according to the size information (for example, the aspect ratio of the original picture is calculated), and when the picture proportion of the original picture is within the preset proportion range, the display picture is obtained by processing the original picture by adopting the display picture generating method of the present invention, and the display picture is displayed.
In practical application, for example, in the report resource management platform, when the proportion of the original picture does not meet the picture filling condition, a picture with the same picture size as the target size of the picture can be randomly selected from a preset picture library to be displayed as a report cover.
S120: and determining a region to be filled of the display picture corresponding to the original picture according to the original picture and the picture target size.
In the embodiment of the present invention, the picture size of the display picture is the same as the target size of the picture, and the display picture may include the content of the original picture and at least one region to be filled.

superposing the scaled original picture and the blank picture to generate a display picture corresponding to the original picture;
and taking the blank area in the display picture as the area to be filled.
Specifically, when the scaled original picture is overlapped with the blank picture, the scaled original picture may be centrally placed above the blank picture to be overlapped, so as to generate the display picture.
In an example, when the original picture is scaled in conjunction with fig. 2 of the specification, the width dimension of the scaled original picture may be equal to the width dimension of the blank picture, and the height dimension is smaller than the height dimension of the blank picture. When the scaled original picture and the blank picture are overlapped, the scaled original picture can be placed above the blank picture in a centered manner to be overlapped, so that an upper blank area and a lower blank area are obtained and serve as areas to be filled.
It should be noted that, according to the difference between the size information of the original picture and the target size of the picture, the determined positions of the regions to be filled of the display picture corresponding to the original picture may be different, for example, the positions may be an upper region, a lower region, a left region, a right region, or an annular region around the original picture.
S130: and reading pixel point information in the original picture.
In the embodiment of the present invention, the pixel information may include a color value of the pixel, where the color value of the pixel may be represented by a vector formed by a Red Green Blue (RGB) value and transparency of the pixel, and if transparency of the picture is not considered, the color value may also be directly represented by a vector of RGB color values of the pixel.
In one possible embodiment, the reading the pixel information in the original picture may include reading a preset number of rows of pixel information near a boundary in the original picture. Specifically, the method may include reading pixel point information of a preset number of rows (e.g., 5 rows) in the original picture, which is close to a boundary adjacent to the region to be filled. For example, if the region to be filled is an upper region and a lower region, pixel point information of preset rows of the upper boundary and the lower boundary of the original picture can be read; if the region to be filled is a left region and a right region, pixel point information of preset rows of left and right boundaries in the original picture can be read; if the region to be filled is an annular region around the original picture, pixel point information of preset rows of all boundaries of the original picture can be read.
It should be noted that, in some possible embodiments, the reading the pixel information in the original picture may also include reading pixel information of a certain area inside the original picture.
S140: and determining the dispersion degree of the pixel colors in the original picture according to the pixel information.

In the embodiment of the invention, all the pixel point information can be ordered according to the distance between the pixel point information and the first pixel point information to obtain an ordering result, and the first 90% of the pixel point information (namely, the pixel point information with the minimum distance between the pixel point information and the first pixel point information) in the ordering result is acquired to form a target pixel point information set, so that the influence of some high-contrast patterns on the determination of the filling mode of the picture can be removed.
S333: and calculating a second moment of the target pixel information set and the first pixel information, and taking the second moment as the dispersion of the pixel colors in the original picture.
In the embodiment of the invention, the second moment can represent the fluctuation of the pixel point information in the target pixel point information set near the first pixel point information, can be used for measuring the dispersion of all the pixel point information in the target pixel point information set, and can be used as the dispersion of the pixel point colors in the original picture.
S150: and selecting a picture filling mode of the display picture corresponding to the original picture according to the dispersion.
In the embodiment of the invention, the picture filling mode of the display picture corresponding to the original picture can be selected from a preset method library according to the complexity degree of the pixel point color in the original picture. The preset method library comprises fuzzy filling and solid-color filling, when the color of the pixel points in the original picture is single, the solid-color filling is adopted, so that the filling part and the content of the original picture are seamlessly connected and fused, and when the color of the pixel points in the original picture is complex, the fuzzy filling is adopted, so that the filled display picture is softer, and abrupt cracking sense is avoided.
In the embodiment of the present invention, the picture filling method for selecting the display picture corresponding to the original picture according to the dispersion may include:

and when the dispersion is larger than a first preset threshold value, determining that the picture filling mode of the display picture corresponding to the original picture is fuzzy filling.
The first preset threshold may be set according to an empirical value, for example, may be set to 300. When the dispersion is smaller than or equal to a first preset threshold value, the pixel point color in the original picture is illustrated to be single, so that the picture filling mode of the display picture corresponding to the original picture can be determined to be solid color filling. When the dispersion is larger than a first preset threshold, the pixel point color in the original picture is described as complex, so that the picture filling mode of the display picture corresponding to the original picture can be determined to be fuzzy filling.

S1631: and filling the region to be filled with the pixel point color corresponding to the second pixel point information to generate the display picture.
In the embodiment of the invention, the pixel point color corresponding to the second pixel point information can be used as the filling color to fill all the areas to be filled, and the original picture and the areas to be filled can be spliced to generate the display picture.
In an example, referring to fig. 6 of the specification, the display picture includes an upper region and a lower region to be filled, and when the solid color filling method is used, the region to be filled can be directly filled with the pixel point color corresponding to the second pixel point information, so as to generate the display picture.

In the embodiment of the present invention, the second preset threshold may be set empirically, for example, may be set to 0.8. If the ratio is smaller than or equal to a second preset threshold, the number of boundary noise of the original picture is larger, and the pixel color corresponding to the second pixel information can be used for covering all pixel colors in a certain range (such as a 5-row pixel range) on the boundary of the original picture.

In one possible embodiment, after the display picture is generated, the display picture may be displayed in a specified picture display interface.
In one example, referring to fig. 8 of the drawings, a schematic diagram of a picture display interface provided by an embodiment of the present invention is shown, where the resource management interface 81, the resource interface 82 and the resource detail page 83 of the report resource management platform on the personal computer (Personal Computer, PC) side each include a plurality of picture display areas 84, and the picture display areas 84 are used to display the display pictures.
