Interesting, is that how google rev img search works? I was trying to find a usecase for this tech. I thought google maybe hashed files and searched thatway, but thumbnails dont always turn up results. I thought maybe they just used pagesource data or metadata to find the same pictures because it doesnt work on all images. Maybe this library can fix that

It's more complicated than a hash, but who knows what their proprietary engine uses. Here are some guesses. https://www.quora.com/What-is-the-algorithm-used-by-Googles-reverse-image-search-i-e-search-by-image https://www.quora.com/What-is-the-algorithm-used-by-Googles-... Regardless of how that process works, once Google scrapes an image, they can store some metadata similar to the output of your software, so that it may be used for sorting the much smaller set of images returned by the image similarity algorithm. The top result can then be deemed the "most original" image since it contains the most detail, and the webpage it was found on can get a boost of pagerank or something.
