Witryna4 mar 2013 · I have currently been trying to hash an image from my browser using javascript. However, I've been hashing a string of the dataURL or the pixel data that I've been retrieving from the canvas element in HTML. This is obviously not the same as hashing the raw data of the image which is what I would like to do. Witryna27 lis 2015 · I need a (preferably simple and fast) image hashing algorithm. The hash value is used in a lookup table, not for cryptography. Some of the images are "computer graphic" - i.e. solid-color filled rects, rasterized texts and etc., whereas there are also "photographic" images - containing rich color spectrum, mostly smooth, with …
