Detailed Description

template<class T>
class kmeans::KMeansSegmenter< T >::Pruner

Controls pruning of regions based on size.

The choice of best region is made through comparing measure distance.

Public Types
typedef std::set< int >	Alternates
Public Member Functions
	Pruner (const KMeansSegmenter< T > &seg, const LImage< int > &label, const ImageAttr< T > &attr, size_t min_size=10)
virtual	~Pruner ()
const Segmenter::Replacement &	getReplacement () const
	Get the result after pruning, i.e.
Protected Member Functions
virtual bool	shouldRemoveRegion (int reg_label) const
	The method that should be over-ridden to tell removeRegions whether to remove a region.
virtual int	getReplacementLabel (int current_label, const std::set< int > &alternates) const
	The method that should be over-ridden to provide the way of choosing the alternate label to removeRegions.
virtual void	confirmRemoval (vector< RegionPruner::Alternates > &remain, vector< RegionPruner::Alternates > &goaway, vector< bool > &should_remove_this_region) const
	Changes the regions to be prune after seeing the consequences.
virtual void	recompute (const std::vector< int > &replacements)
	Recomputes internal data after one pass of pruning.
virtual void	getClosebyRegions (int regNo, std::set< int > *closeby)
	uses a cluster relativeDist threshold of 0.3 to decide.

Member Function Documentation

template<class T>

virtual void kmeans::KMeansSegmenter< T >::Pruner::confirmRemoval	(	vector< RegionPruner::Alternates > &	remain,
		vector< RegionPruner::Alternates > &	goaway,
		vector< bool > &	should_remove_this_region
	)			const [protected, virtual]

Changes the regions to be prune after seeing the consequences.

Tries to add the bunch of regions to meet size requirements.

template<class T>

virtual void kmeans::KMeansSegmenter< T >::Pruner::getClosebyRegions	(	int	regNo,
		std::set< int > *	closeby
	)			[protected, virtual]

uses a cluster relativeDist threshold of 0.3 to decide.

Reimplemented from kmeans::Segmenter::RegionPruner.

const Segmenter::Replacement& kmeans::Segmenter::RegionPruner::getReplacement

(

)

const [inline, inherited]

Get the result after pruning, i.e.

after a call to Segementer::pruneRegions.

template<class T>

virtual int kmeans::KMeansSegmenter< T >::Pruner::getReplacementLabel	(	int	current_label,
		const std::set< int > &	alternates
	)			const [protected, virtual]

The method that should be over-ridden to provide the way of choosing the alternate label to removeRegions.

The set of alternatives will not include candidates for removal, and therefore can be empty.

Implements kmeans::Segmenter::RegionPruner.

template<class T>

virtual void kmeans::KMeansSegmenter< T >::Pruner::recompute

(

const std::vector< int > &

replacements

)

[protected, virtual]

Recomputes internal data after one pass of pruning.

Implements kmeans::Segmenter::RegionPruner.

template<class T>

virtual bool kmeans::KMeansSegmenter< T >::Pruner::shouldRemoveRegion

(

int

reg_label

)

const [protected, virtual]

The method that should be over-ridden to tell removeRegions whether to remove a region.

Implements kmeans::Segmenter::RegionPruner.
