Detailed Description

template<typename TScalarType, unsigned int NDimensions = 3>
class itk::DasGradientFilter< TScalarType, NDimensions >

This class calculates the gradient as per equation 3 in Das et. al. Neuroimage 45 (2009) 867-879.

The inputs should be exactly as follows

1. WM PV map, set using SetInput(0, image)
2. G+W PV map, set using SetInput(1, image)
3. Thickness prior map, set using SetInput(2, image)
4. Thickness image, set using SetInput(3, image)
5. Phi transformation, set using SetTransformation(image) as this is a vector image.
