template<typename TInputImage , typename TCoordRep = float>
virtual::itk::LightObject::Pointer itk::VectorCentralDifferenceImageFunction< TInputImage, TCoordRep >::CreateAnother ( void  ) 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 = float>
virtual OutputType itk::VectorCentralDifferenceImageFunction< TInputImage, TCoordRep >::Evaluate ( const PointType point) const
inlinevirtual

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.

The UseImageDirection flag determines whether image derivatives are computed with respect to the image grid or with respect to the physical space. When this flag is ON the derivatives are computed with respect to the coordinate system of physical space. The difference is whether we take into account the image Direction or not. The flag ON will take into account the image direction and will result in an extra matrix multiplication compared to the amount of computation performed when the flag is OFF. The default value of this flag is On.
