◆ PyramidFilterCentered()

void PyramidFilterCentered	(	double	g[],
		long *	ng,
		double	h[],
		long *	nh,
		long	Order
	)

PyramidFilterCentered. Function: PyramidFilterCentered

Purpose: Initializes down- and up-sampling filter arrays for least squares CENTERED splines of order 0 to 4. (little l_2 norm) g : reduce filter h : expand filter

Note: filter arrays should be defined as double g[20],h[20] filter arrays short *ng,*nh; number of taps short Order; order of the spline

◆ PyramidFilterCenteredL2()

void PyramidFilterCenteredL2	(	double	g[],
		long *	ng,
		double	h[],
		long *	nh,
		long	Order
	)

PyramidFilterCenteredL2. Function: PyramidFilterCenteredL2

Purpose: Initializes the symmetric down- and up-sampling filter arrays for L2 spline pyramid of order 0 to 5 when the downsampled grid is centered. These filters have then to be followed by a Haar filter. g: reduce filter h: expand filter

Note: filter arrays should be defined as float g[35],h[35] filter arrays short *ng,*nh number of taps short Order order of the spline

◆ PyramidFilterCenteredL2Derivate()

void PyramidFilterCenteredL2Derivate	(	double	g[],
		long *	ng,
		double	h[],
		long *	nh,
		long	Order
	)

PyramidFilterCenteredL2Derivate. Function: PyramidFilterCenteredL2Derivate

Purpose: Initializes the symmetric down- and up-sampling filter arrays for L2 DERIVATIVE spline pyramid of order 0 to 5 when the downsampled grid is centered. These filters have then to be followed by a Derivative Haar filter. g : reduce filter h : expand filter Note: filter arrays should be defined as float g[35],h[35] filter arrays short *ng,*nh number of taps short Order order of the spline
