virtual

Executes the segmentation strategy over region delimited by the given block.

Parameters

segmenterIdsManager	The segments IDs manager to be used when acquiring/releaseing unique segment IDs.
block2ProcessInfo	The information about the block of raster that must be processed.
inputRaster	Input raster.
inputRasterBands	Input raster bands.
inputRasterNoDataValues	A vector of values to be used as input raster no-data values.
inputRasterBandMinValues	The minimum value present on each band.
inputRasterBandMinValues	The maximum value present on each band.
outputRaster	Output raster.
outputRasterBand	Output raster band.
enableProgressInterface	Enable the internal strategy to update the progress interface.

Returns: true if OK, false on errors.

Note: The used gaind/ofset calcule: new_value = ( old_value + offset ) * gain

Implements te::rp::SegmenterStrategy.

BlocksMergingMethod te::rp::SegmenterRegionGrowingMeanStrategy::getBlocksMergingMethod ( ) const

virtual

Return the strategy blocks merging method.

Returns: The blocks merging method.

Implements te::rp::SegmenterStrategy.

double te::rp::SegmenterRegionGrowingMeanStrategy::getMemUsageEstimation	(	const unsigned int	bandsToProcess,
		const unsigned int	pixelsNumber
	)		const

virtual

Returns a memory estimation (bytes).

This parameter is used by the segmenter to guess the sub-image blocks size.

Parameters

bandsToProcess	The number of input raster bands that will be processed at the strategy execution time.
pixelsNumber	The number of pixels.

Returns: A positive memory use estimation.

Implements te::rp::SegmenterStrategy.

unsigned int te::rp::SegmenterRegionGrowingMeanStrategy::getOptimalBlocksOverlapSize ( ) const

virtual

Returns a optimal blocks overlap size (number of border pixels overlapped between blocks, under one direction).

Note: This value will be used in the case where the image is splitted into blocks for segmentation.

Returns: The blocks overlap size.

Implements te::rp::SegmenterStrategy.

bool te::rp::SegmenterRegionGrowingMeanStrategy::initialize	(	SegmenterStrategyParameters const *const	strategyParams	)
throw	(	te::rp::Exception
	)

virtual

Initialize the segmentation strategy.

Parameters

strategyParams A pointer to the user given specific segmentation strategy parameters ou NULL if no parameters are present.

Returns: true if OK, false on errors.

Implements te::rp::SegmenterStrategy.

bool te::rp::SegmenterRegionGrowingMeanStrategy::initializeSegments	(	SegmenterIdsManager &	segmenterIdsManager,
		const te::rp::SegmenterSegmentsBlock &	block2ProcessInfo,
		const te::rst::Raster &	inputRaster,
		const std::vector< unsigned int > &	inputRasterBands,

		const std::vector< std::complex< double > > &	inputRasterBandMaxValues,
		SegmenterRegionGrowingSegment< rg::MeanFeatureType > **	actSegsListHeadPtr
	)

protected

Initialize the segment objects container and the segment IDs container.

Parameters

segmenterIdsManager	A segments ids manager to acquire unique segments ids.
block2ProcessInfo	Info about the block to process.
inputRaster	The input raster.
inputRasterBands	Input raster bands to use.
inputRasterNoDataValues	A vector of values to be used as input raster no-data values.
inputRasterBandMinValues	The minimum value present on each band.
inputRasterBandMinValues	The maximum value present on each band.
actSegsListHeadPtr	A pointer the the active segments list head.

Returns: true if OK, false on errors.

void te::rp::SegmenterRegionGrowingMeanStrategy::reset ( )

virtual

Clear all internal allocated resources and go back to the initial not-initialized state.

Implements te::rp::SegmenterStrategy.

bool te::rp::SegmenterRegionGrowingMeanStrategy::shouldComputeMinMaxValues ( ) const

virtual

Returns if the min and max pixel values should be computed.

Returns: True if min and max values should be computed. False otherwise.
