Detailed Description

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

This class implements a multi-threaded finite difference image to image solver that can be applied to an arbitrary list of pixels.

This class is intended as a common base class for classical narrowband solvers and manifold solvers. This base class implements a common memory management and multi-threaded architecture for applying a finite difference function to a list of pixels in an image. The specifics of narrowband solvers such as re-initialization and the use of land-mines are not implemented.
INPUTS
This filter takes an itk::Image as input. The appropriate type of input image is entirely determined by the application. As a rule, however, the input type is immediately converted to the output type before processing. This is because the input is not assumed to be a real value type and must be converted to signed, real values for the calculations.
OUTPUTS
The output is an itk::Image and is the solution of the pde. The embedding of the interface may vary with the application, but the usual ITK convention is that it is the zero level set in the output image.
IMPORTANT!
Read the documentation for FiniteDifferenceImageFilter before attempting to use this filter. The solver requires that you specify a FiniteDifferenceFunction to use for calculations. This is set using the method SetDifferenceFunction in the parent class.
