Detailed Description

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

Nearest neighbor interpolation of a scalar image.

NearestNeighborInterpolateImageFunction interpolates image intensity at a non-integer pixel position by copying the intensity for the nearest neighbor. This class is templated over the input image type and the coordinate representation type (e.g. float or double).

virtual::itk::LightObject::Pointer itk::NearestNeighborInterpolateImageFunction< TInputImage, TCoordRep >::CreateAnother ( ) const

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.

template<typename TInputImage , typename TCoordRep = double>

virtual OutputType itk::NearestNeighborInterpolateImageFunction< TInputImage, TCoordRep >::EvaluateAtContinuousIndex ( const ContinuousIndexType & index ) const

inlineoverridevirtual

Evaluate the function at a ContinuousIndex 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.

Implements itk::InterpolateImageFunction< TInputImage, TCoordRep >.

template<typename TInputImage , typename TCoordRep = double>

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
