Problems solved by technology

[0003] When it is necessary to compare images, the pixel values ​​of the images are generally compared directly by hand, so it is difficult to quickly locate the differences in the images
[0004] The comparison is realized by using a program, but because the comparison result is not visualized, it is not clear and intuitive enough, and the comparison process is systematic, so the application is narrow and not convenient enough

Embodiment Construction

[0022] Usually, images (or image files) generated by algorithms or other methods cannot be guaranteed to pass (or be correct) at one time. At this time, it is necessary to compare the generated image files with standard (correct) images to find out the problem. .

[0023] The method of the present invention includes the following processes:

[0024] 1. Preprocessing, converting the image to be analyzed into the same data format containing color values ​​for comparison.

[0025] Due to the variety of image formats and data formats, the specific conversion process can be realized by designing hardware or software based on the image format and data format, based on the technical knowledge in this technical field, such as: converting YUV444 image data to RGB24 image data.

[0026] 2. Compare the color values ​​of the corresponding pixels of the two images one by one, and if they are not the same, it is a point of difference.

[0027] 3. Provide some kind of traversal method to ...

Abstract

The invention is specifically related to a detection method for displaying difference point in image. The method includes following processes: converting image to be analyzed to same data format; comparing color values of pixels in two images one by one; if their values are not same, then difference point is formed; traversing all difference points and displaying their coordinate; distribution of difference points or position (coordinate) of each difference point are displayed visually. The invention visualizes compared result so that position distribution and coordinates of difference points are clear at a glance.

Description

technical field [0001] The present invention relates to an image processing method, in particular to a detection method for an image problem, in particular a detection method for realizing the display of difference points in an image. Background technique [0002] There are many methods for comparing questions in text, but no method for comparing questions in images has been seen. [0003] When there is a need for image comparison, the pixel values ​​of the images are generally compared directly by hand, so it is difficult to quickly locate the differences in the images. [0004] The comparison is realized by using a program, but because the comparison result is not visualized, it is not clear and intuitive enough, and the comparison process is systematic, so the application is narrow and not convenient enough. Contents of the invention [0005] The purpose of the present invention is to provide a method for detecting image problems, which can intuitively obtain informati...
