Detailed Description

template<typename TInputImage, typename TCoordRep = float>
class itk::NearestNeighborExtrapolateImageFunction< TInputImage, TCoordRep >

Nearest neighbor extrapolation of a scalar image.

NearestNeighborExtrapolateImageFunction extrapolate image intensity at a specified point, continuous index or index by copying the intensity of the nearest neighbor within the image buffer.

This class is templated over the input image type and the coordinate representation type (e.g. float or double).

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

Evaluate the function at a ContinuousIndex position

Returns the extrapolated image intensity at a specified position by returning the intensity of the nearest neighbor within the image buffer.
