accum_dist()

template<class T>

template<typename U , typename V >

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

Partial distance, used by the kd-tree.

operator()()

template<class T>

template<typename Iterator1 , typename Iterator2 >

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

Compute the Minkowsky (L_p) distance between two vectors.

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

The computation of squared root at the end is omitted for efficiency.
