Detailed Description

template<class TInputImage, class TOutputImage>
class itk::DenseFiniteDifferenceImageFilter< TInputImage, TOutputImage >

This filter implements a layer of the finite difference solver hierarchy that performs ``dense'' iteration, ie. iteration over all pixels in the input and output at each change calculation and update step. Dense iteration is in contrast to a ``sparse'' iteration over a subset of the pixels. See documenation for FiniteDifferenceImageFilter for an overview of the iterative finite difference algorithm:

The generic code for performing iterations and updates at each time step is inherited from the parent class. This class defines an update buffer for and the methods CalculateChange() and ApplyUpdate(). These methods are designed to automatically thread their execution. is defined as an image of identical size and type as the output image.

As we descend through each layer in the hierarchy, we know more and more about the specific application of our filter. At this level, we have committed to iteration over each pixel in an image. We take advantage of that knowledge to multithread the iteration and update methods.

Inputs and Outputs: This is an image to image filter. The specific types of the images are not fixed at this level in the hierarchy.

How to use this class: This filter is only one layer in a branch the finite difference solver hierarchy. It does not define the function used in the CalculateChange() and it does not define the stopping criteria (Halt method). To use this class, subclass it to a specific instance that supplies a function and Halt() method.

typedef Superclass::FiniteDifferenceFunctionType itk::DenseFiniteDifferenceImageFilter< TInputImage, TOutputImage >::FiniteDifferenceFunctionType

The value type of the time step. This is distinct from PixelType because PixelType may often be a vector value, while the TimeStep is a scalar value.
