Function Documentation

LinearGradient()

int LinearGradient	(	double	InputData[],
		double	OutputGradient[],
		long	SignalLength,
		long	Degree,
		enum TBoundaryConvention	Convention,
		double	Tolerance,
		int *	Status
	)

Compute the gradient of 1D data. InputData and OutputGradient have size SignalLength.

success: return(!ERROR); failure: return(ERROR)

PlanarGradient()

int PlanarGradient	(	float *	InputImage,
		float *	OutputGradient[],
		long	Nx,
		long	Ny,
		long	Degree,
		enum TBoundaryConvention	Convention,
		double	Tolerance,
		int *	Status
	)

Compute the gradient of 2D data. InputImage has size (Nx x Ny). OutputGradient is an array of two elements. Each element of OutputGradient is a (float *) pointer to an image. Each element has size (Nx x Ny). The first element is the gradient along x. The second element is the gradient along y.

success: return(!ERROR); failure: return(ERROR)

VolumetricGradient()

int VolumetricGradient	(	float *	InputVolume,
		float *	OutputGradient[],
		long	Nx,
		long	Ny,
		long	Nz,
		long	Degree,
		enum TBoundaryConvention	Convention,
		double	Tolerance,
		int *	Status
	)

Compute the gradient of 3D data. InputVolume has size (Nx x Ny x Nz). OutputGradient is an array of three elements. Each element of OutputGradient is a (float *) pointer to a volume. Each element of OutputGradient has size (Nx x Ny x Nz). The first element is the gradient along x. The second element is the gradient along y. The third element is the gradient along z.
