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

typedef False cvflann::HammingLUT2::is_kdtree_distance

typedef False cvflann::HammingLUT2::is_vector_space_distance

typedef unsigned char cvflann::HammingLUT2::ElementType

typedef int cvflann::HammingLUT2::ResultType

Member Function Documentation

ResultType cvflann::HammingLUT2::operator()	(	const unsigned char *	a,
		const unsigned char *	b,
		size_t	size
	)		const

this will count the bits in a ^ b
