Image comparison device and method, electronic equipment

Abstract

The embodiment of the present invention provides an image comparison device and method, and electronic equipment. By correcting the offset and proportion of the image according to the characteristics of the webpage image and combining the first judgment method during the correction process, most of the same images can be removed. image, and use the second determination method for further determination, which can further improve the accuracy of the comparison result, and the comparison speed is faster and the comparison result is more accurate.

Description

technical field

[0001] The invention relates to the field of information technology, in particular to an image comparison device and method, and electronic equipment. Background technique

[0002] With the continuous development of information technology, the application of image processing in various fields is becoming more and more extensive. In many cases, it is necessary to compare two images to determine whether the two images are the same image and the degree of difference between the two images.

[0003] For example, with the development of network technology, web pages have become one of the main sources of information in daily life. A common problem faced by web designers is unreliable cross-platform web rendering. For the same URL, browsers with different types or the same type but different versions have more or less differences in the appearance of the opened webpage. Currently, comparison and difference detection of web pages is generally based on source file...

Embodiment 1

[0024] An embodiment of the present invention provides an image comparison device, figure 1 is a schematic diagram of the image comparison device according to Embodiment 1 of the present invention. like figure 1 As shown, the detection device 100 includes:

[0025] The first determination unit 101 is configured to use the first determination method to perform the first first determination on the pre-acquired image pair to be compared, and determine that the two images in the image pair to be compared satisfying the preset condition are the same image ;

[0026] The first correction unit 102 is configured to estimate the position offset between the two images in the image pair to be compared for the image pair to be compared that does not meet the preset condition after the first first determination, and calculate the position The offset is corrected, and the image pair to be compared after the position offset correction is provided to the first determination unit 101 for th...

Embodiment 2

[0074] The embodiment of the present invention also provides an electronic device, Figure 4 It is a schematic diagram of the electronic device of Embodiment 2 of the present invention. Such as Figure 4 As shown, the electronic device 400 includes an image comparison device 401.
