Computes average hash value of the input image
This is a fast image hashing algorithm, but only work on simple case.
Image hash based on block mean.
Image hash based on color moments.
The base class for image hash algorithms
Marr-Hildreth Operator Based Hash, slowest but more discriminative.
Slower than average_hash, but tolerant of minor modifications
This algorithm can combat more variation than averageHash, for more details please refer to CITE: lookslikeit
Image hash based on Radon transform.
