This is a demo of a bit of research I did that didn’t really go anywhere but I thought it was interesting so I made a demo out of it. I wanted to improve reverse image search on edited images and photobashed images. I thought it was neat that the algorithm only uses highschool math and the global minimum is found analytically.

I did a demo a few years ago on similar work which made it to the hm front page here: https://news.ycombinator.com/item?id=14973741

This demo was hard to write. It was really hard to not to either over or under explain the algorithm. For some this will be a really simple algorithm that could be summed up in a few sentences and for others it’ll require remembering some math they haven’t seen since college or highschool. It gave me an even bigger appreciation for how well YouTubers like 3blue1brown can explain mathematical concepts.

Hope you guys enjoy it
