image-comparison
A Java library for comparing two images of the same size, visually highlighting differences with configurable rectangles, ideal for automated QA testing.
What is image-comparison?
Image-comparison is a Java library that compares two images of identical dimensions and visually highlights differences by drawing rectangles around them. It solves the problem of detecting visual regressions in applications by providing a programmatic way to validate image consistency. The library is configurable, allowing exclusion of specific areas and adjustment of pixel tolerance levels.
Java developers and QA engineers building automated visual testing pipelines, particularly those working on applications where UI consistency is critical.
Developers choose Image-comparison for its simplicity, lack of external dependencies, and fine-grained configurability, making it a reliable and lightweight tool for integrating visual comparison into automated tests.
Overview
Published on Maven Central Java Library that compares 2 images with the same sizes and shows the differences visually by drawing rectangles. Some parts of the image can be excluded from the comparison. Can be used for automation QA tests.
