Butteraugli – estimate the psychovisual difference between two images

Butteraugli is a project that estimates the psychovisual similarity of two images. Y’all likely know that there are very different results from app to app if you use for example a JPEG-compression of 65—in one app this looks still perfectly fine while others already create unbearable artifacts. Butteraugli tries to solve this by creating a standardized comparison of two images and even claims to work better than SSIM.
