US 2026/0203864 A1 · IMAGE COMPARATOR WITH DIFFERENCE AREA LABELING

Abstract

An image difference generator can receive first and second images of first and second display outputs of a computer program, such as a webpage. The images can contain two different categories of differences, one related to the differences in the webpage code, and one related to the differences unrelated to the webpage code, such as differences due to environmental, platform, or generally indeterministic sources, unrelated to the webpage code. The image difference generator can identify each category of the differences and their corresponding regions in each image, and highlight them differently in an output difference image. A developer of the software or webpage can inspect the output difference image and focus her development activity on the appropriate category.

Dependent claims

A method comprising:

receiving first and second images;
generating first and second context images;
generating an inverted first context image;
generating a combined context image by combining the inverted first context image with the second context image;
generating an inverted combined context image;
generating a preliminary difference image from the first and second images, the preliminary difference image, comprising an identification of difference pixels between the first and second images;
generating a first intermediary difference image by merging the inverted combined context image and the preliminary difference image;
inverting the preliminary difference image;
generating a second intermediary difference image by adding the inverted preliminary difference image to the combined context image;
generating a combined difference image by adding the first and second intermediary difference images;
and
generating and displaying an output difference image, based at least in part on the combined difference image.
