Detailed Description

template<class TInput, class TOutput>
class itk::FastMarchingUpwindGradientImageFilterBase< TInput, TOutput >

Generates the upwind gradient field of fast marching arrival times.

This filter adds some extra functionality to its base class. While the solution T(x) of the Eikonal equation is being generated by the base class with the fast marching method, the filter generates the upwind gradient vectors of T(x), storing them in an image.

Since the Eikonal equation generates the arrival times of a wave travelling at a given speed, the generated gradient vectors can be interpreted as the slowness (1/velocity) vectors of the front (the quantity inside the modulus operator in the Eikonal equation).

Gradient vectors are computed using upwind finite differences, that is, information only propagates from points where the wavefront has already passed. This is consistent with how the fast marching method works.
