Detailed Description

template<class TInputImage, class TCoordRep = float>
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 heirarchy of functions work only for images with scalar pixel types. For images of vector pixel types use VectorInterpolateImageFunctions.

Member Function Documentation

template<class TInputImage, class TCoordRep = float>
virtual OutputType itk::InterpolateImageFunction< TInputImage, TCoordRep >::Evaluate (  const PointType &    point )  const [inline, virtual]
 

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.
