The embodiment of the application provides a difference area positioning method, which can be executed by a processor of a terminal, as shown in fig. 2, and the specific flow of the difference area positioning method mainly comprises steps 201 to 204, and is described in detail as follows:
step 201, a first display picture and a second display picture are obtained.

In addition, the picture content in the first display picture and the second display picture is not limited, and the display data of the first display picture and the second display picture are different. For example, in the schematic diagrams of the first display picture and the second display picture shown in fig. 3, the first display picture 301 and the second display picture 302 are the same menu interface of the electronic device, and the areas selected by the movable cursors in the first display picture 301 and the second display picture 302 are different.

Step 202, according to the pixel value difference between each pixel block in each display picture and the adjacent pixel block, adjusting the pixel value of each pixel block in each picture to obtain a first processing display picture and a second processing display picture.
In the embodiment of the present application, the degree of change of the pixel values of each pixel block and the adjacent pixel block in each picture may be determined according to the difference between the pixel values of each pixel block and the pixel values of the adjacent pixel block in each picture, so as to adjust the pixel values of each pixel block in each picture, specifically, in step 202, "according to the difference between the pixel values of each pixel block and the adjacent pixel block in each display picture, the pixel values of each pixel block in each picture are adjusted, so as to obtain a first processed display picture and a second processed display picture," may be:

the first pixel value of each first pixel block in the first display picture is differenced with the first pixel value of the adjacent pixel block to form a plurality of first difference values, and the second pixel value of each second pixel block in the second display picture is differenced with the second pixel value of the adjacent pixel block to form a plurality of second difference values;
And adjusting pixel values of the first pixel blocks of the first display picture according to the first difference value to enable the color of the first display picture to be changed into a first color and a second color, obtaining the first processing display picture, and adjusting pixel values of the second pixel blocks of the second display picture according to the second difference value to enable the color of the second display picture to be changed into the first color and the second color, and obtaining the second processing display picture.
In the embodiment of the present application, the adjacent pixel block of a pixel block may be a pixel block having a common edge and/or a common vertex with the pixel block in the picture. Since the number of adjacent pixel blocks of one pixel block is plural, that is, the difference between the pixel block and each adjacent pixel block is calculated.
In the embodiment of the present application, the pixel value is a value given by a computer when the document image is digitized, and represents the average luminance information of a certain small square of the document, or the average reflection (transmission) density information of the small square.
In an embodiment of the present application, the step of "adjusting the pixel value of each of the first pixel blocks of the first display picture according to the first difference value so that the color of the first display picture becomes a first color and a second color, obtaining the first processed display picture, and adjusting the pixel value of each of the second pixel blocks of the second display picture according to the second difference value so that the color of the second display picture becomes the first color and the second color, obtaining the second processed display picture" may be:
Acquiring a first contrast pixel threshold value of the first pixel block and an adjacent pixel block in the first display picture, and acquiring a second contrast pixel threshold value of the second pixel block and an adjacent pixel block in the second display picture;
comparing a first difference value related to each first pixel block in the first display picture with the first contrast pixel threshold according to a first preset sequence, if the first difference value is smaller than the first contrast pixel threshold, determining that the first difference value smaller than the first contrast pixel threshold is a first reference difference value, and adjusting pixel values of the first pixel block and adjacent pixel blocks forming the first reference difference value by making differences to be pixel values corresponding to the first color or pixel values corresponding to the second color;
if the first difference value is larger than the first contrast pixel threshold value, determining that the first difference value larger than the first contrast pixel threshold value is a second reference difference value, and adjusting one pixel value to be the pixel value corresponding to the first color and the other pixel value to be the pixel value corresponding to the second color in the pixel values of a first pixel block and the adjacent pixel blocks which are subjected to difference forming to the second reference difference value;
Obtaining the first processing display picture according to the adjusted first pixel block;
comparing a second difference value related to each second pixel block in the second display picture with the second comparison pixel threshold according to a second preset sequence, if the second difference value is smaller than the second comparison pixel threshold, determining that the second difference value smaller than the second comparison pixel threshold is a third reference difference value, and adjusting pixel values of the second pixel block and adjacent pixel blocks forming the third reference difference value by making differences to be pixel values corresponding to the first color or pixel values corresponding to the second color;
if the second difference value is larger than the second contrast pixel threshold value, determining that the second difference value larger than the second contrast pixel threshold value is a fourth reference difference value, and adjusting one pixel value to be the pixel value corresponding to the first color and the other pixel value to be the pixel value corresponding to the second color in the pixel values of a second pixel block and an adjacent pixel block of the fourth reference difference value formed by making the difference;
and obtaining the second processing display picture according to the adjusted second pixel block.
The first color and the second color refer to two different colors, which can be white and black, respectively, that is, if the first color is set to be white, the second color is set to be black. If the first color is set to be black, the second color is set to be white. I.e. the first display picture and the second display picture are changed from the original color to a picture having only black and white.
For example, adjacent pixel blocks of a target pixel block a in the first display picture are an adjacent pixel block B, an adjacent pixel block C and an adjacent pixel block D, a first difference value l is obtained by making a difference between first pixel values of the target pixel block a and the adjacent pixel block B, a first difference value m is obtained by making a difference between first pixel values of the target pixel block a and the adjacent pixel block C, a first difference value n is obtained by making a difference between first pixel values of the target pixel block a and the adjacent pixel block D, and a first contrast pixel threshold value t of the first display picture is set. If the first difference value l is smaller than the first contrast pixel threshold t, the pixel value change degree between the target pixel block a and the adjacent pixel block B is smaller, the pixel value of the target pixel block a and the pixel value of the adjacent pixel block B are set to be the same color (white or black), if the first difference value m is larger than the first contrast pixel threshold t, the pixel value change degree between the target pixel block a and the adjacent pixel block C is larger, the pixel value of the target pixel block a and the pixel value of the adjacent pixel block C are set to be different colors (i.e. if the target pixel block a is black, the adjacent pixel block C is white, and vice versa), and if the first difference value n is smaller than the first contrast pixel threshold t, the pixel value change degree between the target pixel block a and the adjacent pixel block D is set to be the same color (white or black). Similarly, the same steps are also adopted for each target pixel block in the second display picture, so that the first display picture and the second display picture are set to be pictures only including black and white colors, and as shown in the schematic diagrams of the first processing display picture and the second processing display picture in fig. 4, the first processing display picture 401 is generated by the first display picture 301 in fig. 3 according to the pixel value variation degree of each pixel block and the adjacent pixel block, and the second processing display picture 402 is generated by the second display picture 302 in fig. 3 according to the pixel value variation degree of each pixel block and the adjacent pixel block.
In the embodiment of the present application, the first preset sequence is a selection sequence of the first pixel block when comparing the first difference value related to the first pixel block with the first contrast pixel threshold value in sequence. The first preset sequence is not limited and can be flexibly set according to practical situations, for example, the first preset sequence can be set in the first display picture to compare the first difference value related to each first pixel block with the first contrast pixel threshold value in sequence from left to right and from top to bottom. Similarly, the second preset sequence is the selection sequence of the second pixel block when comparing the second difference value related to the second pixel block with the second contrast pixel threshold value in turn. The second preset sequence is not limited and can be flexibly set according to practical situations, for example, the second preset sequence can be set in the second display picture to compare the second difference value related to each second pixel block with the second comparison pixel threshold value in sequence from left to right and from top to bottom. In addition, the first preset sequence and the second preset sequence may be the same or different.
In the embodiment of the application, the setting of the first contrast pixel threshold value and the second contrast pixel threshold value is not limited, and the setting can be flexibly set according to actual conditions. The first contrast pixel threshold and the second contrast pixel threshold may be the same or different.
Step 203, obtaining picture difference information between the first processing display picture and the second processing display picture.
In the embodiment of the present application, the first processing display picture and the second processing display picture may be compared according to the pixel values of the pixel blocks at the positions corresponding to the first processing display picture and the second processing display picture, so as to obtain the picture difference information, and specifically, in the step 203, "obtaining the picture difference information between the first processing display picture and the second processing display picture" may be:
the pixel values of the pixel blocks at the corresponding positions of the first processing display picture and the second processing display picture are subjected to difference to obtain corresponding difference values;
and taking the pixel block with the difference value not being zero as the picture difference information.
Step 204, determining a difference region between the first display picture and the second display picture according to the picture difference information.
In the embodiment of the application, different points which are scattered may exist in the first processing display picture and the second processing display picture, in order to avoid that the different points which are scattered in the first processing display picture and the second processing display picture affect the judgment of the difference area, the first processing display picture and the second processing display picture can be processed by using a corrosion algorithm, and the points which are scattered in the first processing display picture and the second processing display picture are removed, namely the points which are scattered in the first processing display picture and the second processing display picture are denoised. Specifically, the determining the difference region between the first display picture and the second display picture according to the picture difference information in the step 204 may include:
Performing corrosion calculation on the first processing display picture and the second processing display picture according to the picture difference information to obtain a corroded first processing display picture and a corroded second processing display picture;
comparing the corroded first processing display picture with the corroded second processing display picture, and determining a first reference difference area between the corroded first processing display picture and the corroded second processing display picture;
and determining the corresponding area of the first reference difference area on the first display picture and the second display picture as the difference area.
In the embodiment of the application, the corroded first processing display picture and the corroded second processing display picture can be obtained by respectively performing corrosion calculation on the first processing display picture and the second processing display picture at least once. Since most of scattered difference points in the corroded first processing display picture and the corroded second processing display picture are removed, the corroded first processing display picture and the corroded second processing display picture are compared again, the difference region of the corroded first processing display picture and the corroded second processing display picture can be obtained, and the difference region between the first display picture and the second display picture is further obtained.
The corrosion calculation means that the highlight part of the original image (the first processing display image and the second processing display image) is corroded, the boundary points of the pixel connection components are removed, so that the original image is reduced by one layer, backbone information of the original image can be extracted, burrs of the original image are removed, isolated pixel points in the original image are removed, and the highlight area in the original image is gradually reduced.
In the embodiment of the present application, in order to make the target edges in the corroded first processing display picture and the corroded second processing display picture smoother, the method may further perform at least one expansion calculation on the corroded first processing display picture and the corroded second processing display picture, and specifically, after performing corrosion calculation on the first processing display picture and the corroded second processing display picture according to the picture difference information to obtain the corroded first processing display picture and the corroded second processing display picture, the method further includes:
performing expansion calculation on the corroded first processing display picture and the corroded second processing display picture to obtain an expanded first processing display picture and an expanded second processing display picture;
Comparing the expanded first processed display picture with the expanded second processed display picture, and determining a second reference difference region between the expanded first processed display picture and the expanded second processed display picture;
and determining the corresponding area of the second reference difference area on the first display picture and the second display picture as the difference area.
In the embodiment of the present application, since the corresponding regions on the first display picture and the second display picture may be irregular regions according to the first reference difference region or the second reference difference region, a minimum rectangle containing the corresponding irregular regions may be set as the difference region.
In the embodiment of the application, the expansion calculation means that the highlight part of the original image (the first processing display image and the second processing display image) is expanded, which is to enlarge the boundary of each pixel connecting component by one layer and fill the hole at the edge of the original image or in the isolated pixel in the original image, so that the highlight area in the original image is gradually enlarged.
