Detailed Description

template<class TInputImage, class TOutputImage, class TInternalPixel = double>
class itk::GradientVectorFlowImageFilter< TInputImage, TOutputImage, TInternalPixel >

This class computes a diffusion of the gradient vectors for graylevel or binary edge map derive from the image. It enlarges the capture range of the gradient force and make external force derived from the gradient work effectively in the framework of deformable model.
