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

Member Typedef Documentation

◆ ElementType

typedef unsigned char cvflann::HammingLUT::ElementType

◆ is_kdtree_distance

◆ is_vector_space_distance

◆ ResultType

Member Function Documentation

◆ 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
