I've already implemented this algorithm and it works pretty well!
For now i can compare one image against many to find similar images. I need now to think on a way to compare a group of images against each other to find the duplicates...
I had an idea on how to implement a "duplicate file finder" feature on Hirobooru that i guess it could work reasonably well
I could resize each image to 10x10px, turn it to grayscale and store the gray values in an array. Then when comparing images i could see which have the gray values most close to each other... ![]()
I'm not sure if that's how it's supposed to be done but i just thought of that.
