void stira::filter::SeparableFilter::BasicFilter1D	(	double *	pInputArray1D,
		double *	pFilterKernel,
		double *	pOutputArray1D,
		int	inputLength,
		int	filterLength,
		GridExtender< double >::ExtensionType	myType = `GridExtender<double>::EXTEND_MIRROR`
	)

static

Filters a one dimensional data set (a single row or column)

Parameters

pInputArray1D	1D input array to filter (a row or a column of the image)
pFilterKernel	the 1D filter kernel
pOutputArray1D	output array after filtering
inputLength	length of the 1D array
filterLength	length of the filter
myType	identifies how borders should be extended (mirror, tile, black)

bool stira::filter::SeparableFilter::RunColumn	(	ArrayGrid< double > *	pInputBand,
		ArrayGrid< double > *	pOutputBand,
		double *	filty,
		int	filterLengthY,
		GridExtender< double >::ExtensionType	myType = `GridExtender<double>::EXTEND_MIRROR`
	)

static

Applies column by column filtering on a single grid with 1 1D filter kernel.

Parameters

pInput	the input grid
pOutput	the output grid (allocated but not necessarely initialized)
filty	the 1D filter taps
filterLengthY	length of the filter
myType	identifies how borders should be extended (mirrored, tiled, padded with zeros)

If the filter length is 1, the output grid is just a copy of the input grid

filterLengthX	length of the filter for the x direction
filterLengthY	length of the filter for the y direction
myType	identifies how borders should be extended (mirror, tile, black)

mallocs memory and returns response of input image filtered with filterTapX on the rows and filterTapY on the columns
