This is fantastic, and I was just wondering if something like existed a week ago. Sometimes I need to find the original picture of a thumbnail on the internet, so I use Google reverse image search to search for other sizes of my uploaded image. However, some websites simply upscale the low quality image in order to be at the top of the search results. I wonder if Google can use a technology like this to place those results on a lower ranking.
- vonklaus 11y agoInteresting, 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
- vortico 11y agoIt'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.
