Detailed Description

template<typename T>
struct lshkit::metric::hamming< T >

Hamming distance.

Take the hamming distance between two bit-vectors, represented as arrays of some basic type. The parameter dim is the size of the bit-vectors in terms of the number of basic types. For example, if we use uchar_t as basic type, then the dim of a 256-bit vector is 256/8 = 32.
