Classes

AverageHash

Computes average hash value of the input image. This is a fast image hashing algorithm, but only work on simple case. For more details, please refer to @cite lookslikeit

BlockMeanHash

Image hash based on block mean.

ColorMomentHash

Image hash based on color moments.

ImgHashBase

The base class for image hash algorithms

MarrHildrethHash

Marr-Hildreth Operator Based Hash, slowest but more discriminative.

PHash

pHash: 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

RadialVarianceHash

Image hash based on Radon transform.
