## Member Typedef Documentation

## ◆ ElementType

template<class T >

typedef T cvflann::L1< T >::ElementType

## ◆ is_kdtree_distance

template<class T >

typedef True cvflann::L1< T >::is_kdtree_distance

## ◆ is_vector_space_distance

template<class T >

typedef True cvflann::L1< T >::is_vector_space_distance

## ◆ ResultType

template<class T >

## Member Function Documentation

## ◆ accum_dist()

template<class T >
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.

## ◆ operator()()

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.
