Image fingerprint to compare similarity of many images

... Normal hashing or CRC calculation algorithms do not work well with image data. The dimensional nature of the information must be taken into account. If you need extremely robust fingerprinting, such that affine transformations (scaling, rotat...

Hash Code and Checksum - what's the difference?

... hash codes may provide a good tradeoff between computation time (close to CRC) and error detection, whether it's intentional or just communication error/bit rot (CRC cannot be expected to detect intentional tampering because it's relatively easy to intentionally design a collision). ...
