Detailed Description

template<class TInputImage, class TCoordRep = float>
class itk::CentralDifferenceImageFunction< TInputImage, TCoordRep >

Calculate the derivative by central differencing.

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

Possible improvements:

• the use of Neighborhood operators may improve efficiency.

Member Function Documentation

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

Evalulate the image derivative by central differencing at non-integer positions. 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::ImageFunction< TInputImage, TOutput, TCoordRep >. Definition at line 98 of file itkCentralDifferenceImageFunction.h. References itk::CentralDifferenceImageFunction< TInputImage, TCoordRep >::IndexType.

template<class TInputImage, class TCoordRep = float> virtual OutputType itk::CentralDifferenceImageFunction< TInputImage, TCoordRep >::EvaluateAtContinuousIndex (  const ContinuousIndexType &  cindex  )  const [inline, virtual]

Evalulate the image derivative by central differencing at non-integer positions. 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::ImageFunction< TInputImage, TOutput, TCoordRep >. Definition at line 104 of file itkCentralDifferenceImageFunction.h. References itk::CentralDifferenceImageFunction< TInputImage, TCoordRep >::ContinuousIndexType, and itk::CentralDifferenceImageFunction< TInputImage, TCoordRep >::IndexType.

template<class TInputImage, class TCoordRep = float> virtual OutputType itk::CentralDifferenceImageFunction< TInputImage, TCoordRep >::EvaluateAtIndex (  const IndexType &  index  )  const [virtual]

Evalulate the image derivative by central differencing at specified index. 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::ImageFunction< TInputImage, TOutput, TCoordRep >.

template<class TInputImage, class TCoordRep = float> virtual const char* itk::CentralDifferenceImageFunction< TInputImage, TCoordRep >::GetNameOfClass (   )  const [virtual]

Run-time type information (and related methods). Reimplemented from itk::ImageFunction< TInputImage, TOutput, TCoordRep >.
