Detailed Description

Blended pixel value calculation for two overlaped rasters.

The overlap between the two images is modeled by the given geometric transformation direct mapping input raster 1 indexed coords (line, column) to input raster 2 indexed coords.

Member Function Documentation

void TePDIBlender::blend	(	const double &	line,
		const double &	col,
		const unsigned int &	rasterChannelsVecsIdx,
		double &	value
	)		`[inline]`

Blend a pixel value using the current parameters.

Parameters:

line	Line (raster 1 reference).
col	Column (raster 1 reference).
rasterChannelsVecsIdx	Vector index (the index to search the correct band/channel for each input raster from raster1ChannelsVec and raster2ChannelsVec).
value	Blended value.

Note:: The caller of this method must be aware that the returned blended value may be outside the original input rasters valid values range.

Examples:: TePDIBlender_test.cpp.

void TePDIBlender::eucBlendMethodImp	(	const double &	line,
		const double &	col,
		const unsigned int &	rasterChannelsVecsIdx,
		double &	value
	)		`[protected]`

bool TePDIBlender::init	(	const TePDITypes::TePDIRasterPtrType &	raster1Ptr,
		const std::vector< unsigned int >	raster1ChannelsVec,
		const TePDITypes::TePDIRasterPtrType &	raster2Ptr,
		const std::vector< unsigned int >	raster2ChannelsVec,
		BlendMethod	blendMethod,
		TePDIInterpolator::InterpMethod	interpMethod,
		const TeGTParams &	transParams,
		const double &	dummyValue,
		const std::vector< double > &	pixelOffsets1,
		const std::vector< double > &	pixelScales1,
		const std::vector< double > &	pixelOffsets2,
		const std::vector< double > &	pixelScales2,
		const TePolygon &	raster1Pol = `TePolygon()`,
		const TePolygon &	raster2Pol = `TePolygon()`
	)

Initiate this instance.

Parameters:

raster1Ptr	Input raster 1 pointer.
raster1ChannelsVec	Input raster 1 bands/channels.
raster2Ptr	Input raster 2 pointer.
raster2ChannelsVec	Input raster 2 bands/channels.
blendMethod	Blending method.
interpMethod	Interpolation method.
transParams	Transformation parameters.
dummyValue	The value to be returned for cases where there is no raster data to blend.
pixelOffsets1	The values offset to be applied to raster 1 pixel values before the blended value calcule (one element for each used raster channel/band).
pixelScales1	The values scale to be applied to raster 1 pixel values before the blended value calcule (one element for each used raster channel/band).
pixelOffsets2	The values offset to be applied to raster 2 pixel values before the blended value calcule (one element for each used raster channel/band).
pixelScales2	The values scale to be applied to raster 2 pixel values before the blended value calcule (one element for each used raster channel/band).
raster1Pol	A polygon (raster 1 indexed coords - line, col) delimiting the raster region with valid data (if an empty polygon is given the entire raster will be considered).
raster2Pol	A polygon (raster 2 indexed coords - line, col) delimiting the raster region with valid data (if an empty polygon is given the entire raster will be considered).

Returns:: true if OK, false on errors.

Note:: Transformation tie-points: TeCoordPair::pt1 are raster 1 indexed (line, column) coordinates and TeCoordPair::pt2 are raster 2 indexed (line, column) coordinates.; raster1ChannelsVec, raster2ChannelsVec, pixelOffsets1, pixelScales1, pixelOffsets2 and pixelScales2 must have the same number of elements.
