Detailed Description

Hamming distance functor - counts the bit differences between two strings - useful for the Brief descriptor bit count of A exclusive XOR'ed with B

operator()()

ResultType cvflann::HammingLUT::operator() ( const unsigned char *  a, const unsigned char *  b, size_t  size  ) const

inline

this will count the bits in a ^ b
