Detailed Description

Abstract base class for any general image interpolation filter.

This is the abstract base class which defines a common interface for all filters which take an image as input and sample that image at arbitrary location. Each derived class has to implement all abstract member functions.

Member Function Documentation

virtual double irtkInterpolateImageFunction::EvaluateInside	(	double	,
		double	,
		double	,
		double	= `0`
	)			`[pure virtual]`

Evaluate the filter at an arbitrary image location (in pixels) without handling boundary conditions.

This version is faster than the method above, but is only defined inside the image domain.

Implemented in irtkBSplineInterpolateImageFunction, irtkBSplineInterpolateImageFunction2D, irtkCSplineInterpolateImageFunction, irtkCSplineInterpolateImageFunction2D, irtkGaussianInterpolateImageFunction, irtkGaussianInterpolateImageFunction2D, irtkLinearInterpolateImageFunction, irtkLinearInterpolateImageFunction2D, irtkNearestNeighborInterpolateImageFunction, irtkNearestNeighborInterpolateImageFunction2D, irtkSincInterpolateImageFunction, and irtkSincInterpolateImageFunction2D.

Bool irtkInterpolateImageFunction::IsInside	(	double	x,
		double	y,
		double	z
	)			`[inline, virtual]`

Check if the location is inside the image domain for which this image interpolation function can be used without handling any form of boundary conditions.
