Detailed Description

template<typename TInputImage, typename TCoordRep = double>
class itk::InterpolateImageFunction< TInputImage, TCoordRep >

Base class for all image interpolaters.

InterpolateImageFunction is the base for all ImageFunctions that interpolates image intensity at a non-integer pixel position. This class is templated over the input image type and the coordinate representation type (e.g. float or double ).

Warning: This hierarchy of functions work only for images with scalar pixel types. For images of vector pixel types use VectorInterpolateImageFunctions.

Interpolate the image at a point position

Returns the interpolated image intensity at a specified point position. No bounds checking is done. The point is assume to lie within the image buffer.

ImageFunction::IsInsideBuffer() can be used to check bounds before calling the method.

Interpolate the image at a continuous index position

Returns the interpolated image intensity at a specified index position. No bounds checking is done. The point is assume to lie within the image buffer.

Subclasses must override this method.

ImageFunction::IsInsideBuffer() can be used to check bounds before calling the method.

Interpolate the image at an index position.

Simply returns the image value at the specified index position. No bounds checking is done. The point is assume to lie within the image buffer.
