template<typename U , typename V >

ResultType cvflann::L1< T >::accum_dist ( const U &  a, const V &  b, int    ) const

inline

Partial distance, used by the kd-tree.

Here is the call graph for this function:

template<class T >

template<typename Iterator1 , typename Iterator2 >

ResultType cvflann::L1< T >::operator() ( Iterator1  a, Iterator2  b, size_t  size, ResultType  worst_dist = -1  ) const

inline

Compute the Manhattan (L_1) distance between two vectors.

This is highly optimised, with loop unrolling, as it is one of the most expensive inner loops.
