Detailed Description

template<class TInputImage>
class rtk::LastDimensionL0GradientDenoisingImageFilter< TInputImage >

Denoises along the last dimension, reducing the L0 norm of the gradient.

This filter implements the "Fast and Effective L0 Gradient Minimization by Region Fusion" method, developped by Nguyen and Brown. Their method is computationally demanding, but its restriction to 1D can be implemented efficiently. This is what this filter does.

Test:
