cvflann::HammingLUT Struct Reference

#include <dist.h>

Public Types

typedef False is_kdtree_distance
 
typedef False is_vector_space_distance
 
typedef unsigned char ElementType
 
typedef int ResultType
 

Public Member Functions

ResultType operator() (const unsigned char *a, const unsigned char *b, int size) const
 

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 unsigned char cvflann::HammingLUT::ElementType

Member Function Documentation

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

this will count the bits in a ^ b
