pixelmatch-rs

Pixel-level image comparison

Completely based on pixelmatch.

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:

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