virtual void kmeans::Segmenter::RegionPruner::getClosebyRegions	(	int	regNo,
		std::set< int > *	closeby
	)			[inline, protected, virtual]

an option function that can be implemented to get closeby regions (other than those that border this one).

Reimplemented in kmeans::KMeansSegmenter< T >::Pruner.

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

(

)

const [inline]

Get the result after pruning, i.e.

after a call to Segementer::pruneRegions.

virtual int kmeans::Segmenter::RegionPruner::getReplacementLabel	(	int	current_label,
		const Alternates &	alternates
	)			const [protected, pure 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.

Implemented in kmeans::KMeansSegmenter< T >::Pruner.

virtual void kmeans::Segmenter::RegionPruner::recompute

(

const Segmenter::Replacement &

replacements

)

[protected, pure virtual]

Recompute any internal data after one pass of pruning.

Implemented in kmeans::KMeansSegmenter< T >::Pruner.

virtual bool kmeans::Segmenter::RegionPruner::shouldRemoveRegion

(

int

reg_label

)

const [protected, pure virtual]

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

Implemented in kmeans::KMeansSegmenter< T >::Pruner.
