Image - an image processing library based upon Vix

I tried to use the Image library to do a fuzzy comparison of two images by using Image.hamming_distance but it was too fuzzy for my purposes — a picture of a cat and a picture of a house got a hamming distance of 0 (they were both relatively small, square, grayscale images).

Any suggestions on a way to do a fuzzy comparison that’s a bit less fuzzy? (Maybe something analogous to the ImageMagick command magick compare -metric AE -fuzz 10% cat.png house.png diff.png ?)
