Detailed Description

template<typename DistanceType>
class cvflann::UniqueResultSet< DistanceType >

Class that holds the k NN neighbors Faster than KNNResultSet as it uses a binary heap and does not maintain two arrays

Constructor & Destructor Documentation

template<typename DistanceType >

cvflann::UniqueResultSet< DistanceType >::UniqueResultSet ( )

inline

Default cosntructor

Member Function Documentation

template<typename DistanceType >

virtual void cvflann::UniqueResultSet< DistanceType >::clear ( )

pure virtual

Remove all elements in the set

Implemented in cvflann::KNNRadiusUniqueResultSet< DistanceType >, cvflann::RadiusUniqueResultSet< DistanceType >, and cvflann::KNNUniqueResultSet< DistanceType >.

template<typename DistanceType >

virtual void cvflann::UniqueResultSet< DistanceType >::copy ( int *  indices, DistanceType *  dist, int  n_neighbors = -1  ) const

inlinevirtual

Copy the set to two C arrays

Parameters

indices	pointer to a C array of indices
dist	pointer to a C array of distances
n_neighbors	the number of neighbors to copy

template<typename DistanceType >

bool cvflann::UniqueResultSet< DistanceType >::full ( ) const

inlinevirtual

Check the status of the set

Returns

true if we have k NN

Implements cvflann::ResultSet< DistanceType >.

Reimplemented in cvflann::RadiusUniqueResultSet< DistanceType >.

template<typename DistanceType >

size_t cvflann::UniqueResultSet< DistanceType >::size ( ) const

inline

The number of neighbors in the set

Returns

template<typename DistanceType >

virtual void cvflann::UniqueResultSet< DistanceType >::sortAndCopy ( int *  indices, DistanceType *  dist, int  n_neighbors = -1  ) const

inlinevirtual

Copy the set to two C arrays but sort it according to the distance first

Parameters

indices	pointer to a C array of indices
dist	pointer to a C array of distances
n_neighbors	the number of neighbors to copy

template<typename DistanceType >

DistanceType cvflann::UniqueResultSet< DistanceType >::worstDist ( ) const

inlinevirtual

The distance of the furthest neighbor If we don't have enough neighbors, it returns the max possible value

Returns

Implements cvflann::ResultSet< DistanceType >.

Reimplemented in cvflann::RadiusUniqueResultSet< DistanceType >.
