"Compare" multiple images

Post by dunnma »

I have a website with thousands of images. I would like to allow someone to upload an image and let them "search" by it returning "matches". Can imagemagick do this? I would need to store something for each of my images, and then compare that with the same something from the search image. Is this a hash, histrogram or something?

Basically is there something I can have imagemagick gather for me that I can store to use for comparison against other images?
