pixelmatch-rs

Pixel-level image comparison

Completely based on [pixelmatch][].

rs let num_diff_pixels = pixelmatch( im1, img2, diff, None, None, Some(Options { threshold: 0.1, ..Default::default() }), );

Implements ideas from the following papers:

• Measuring perceived color difference using YIQ NTSC transmission color space in mobile applications (2010, Yuriy Kotsarenko, Fernando Ramos)
• Anti-aliased pixel and intensity slope detector (2009, Vytautas Vyšniauskas)

Example output

| expected | actual | diff | | --- | --- | --- | | | | | | | | | | | | |

Command line

Pixelmatch comes with a binary that works with PNG images:

bash pixelmatch --threshold 0.1 image1.png image2.png output.png
