odiff compatible pixel-by-pixel image visual difference tool.
The comparison algorithm written entirely in AVX512 assembly.
Currently supports only PNG images, but that's not any inherent limitations.
Very large image file:
./vxdiff ../test-images/funocaml.png ../test-images/funocaml2.png ran
1.04 ± 0.04 times faster than ./odiff ../test-images/funocaml.png ../test-images/funocaml2.png
Very small image file:
./vxdiff /tmp/foo.png /tmp/foo2.png ran
15.10 ± 29.81 times faster than ./odiff /tmp/foo.png /tmp/foo2.png
Image with alpha:
./vxdiff ../test-images/extreme-alpha.png ../test-images/extreme-alpha-1.png ran
2.48 ± 0.37 times faster than ./odiff ../test-images/extreme-alpha.png ../test-images/extreme-alpha-1.png
