bool te::rp::RasterAttributes::execute	(	AlgorithmOutputParameters &	outputParams	)
throw	(	te::rp::Exception
	)

virtual

Executes the algorithm using the supplied parameters.

Parameters

outputParams Output parameters.

Returns: true if OK, false on errors.

Implements te::rp::Algorithm.

Definition at line 54 of file RasterAttributes.cpp.

std::vector< std::complex< double > > te::rp::RasterAttributes::getComplexValuesFromBand	(	const te::rst::Raster &	raster,
		unsigned int	band,
		const te::gm::Polygon &	polygon
	)

Returns the pixel values (real and imag) for the band, inside the polygon.

Parameters

raster	The input raster.
band	The position of the input band.
polygon	The input polygon.

Returns: The pixel values for the band, inside the polygon.

Warning: Band and polygon must fit.

Definition at line 63 of file RasterAttributes.cpp.

std::vector< std::vector< std::complex< double > > > te::rp::RasterAttributes::getComplexValuesFromRaster	(	const te::rst::Raster &	raster,
		const te::gm::Polygon &	polygon,
		std::vector< unsigned int >	bands
	)

Returns the pixel values (real and imag) for all the bands in raster, inside the polygon.

Parameters

raster	The input band.
polygon	The input polygon.
bands	Bands to be processed from the input raster.

Returns: A vector with the pixel values for all the bands in raster, inside the polygon, with values[band][pixel].

Warning: Bands and polygon must fit.

Returns the covariance matrix between vectors of pixel values.

Parameters

vpixels	The vector of pixel vectors, with vpixels[band][pixel].
vmeans	The vector of pixels means, one mean per vector of pixels.

Returns: The covariance matrix between the vectors of pixel values.

Warning: All vectors sizes must fit.
