Hi,
I am wondering myself what is the appropriate speed image for the
fast-marching image filter.
In the "ShapeDetection" example, a GradientRecursiveGaussianImageFilter is
used in conjunction with some exponential damping.
In which correlation are the value in the speed image and the step the
evolving front is going outwards within one timestep?
Regards,
Nils
