public class ROF_Denoise extends Object implements ij.plugin.filter.PlugInFilter
For the included image, a fairly good result is obtained by using a theta value around 12-16. A possible addition would be to analyze the residual with an entropy function and add back areas that have a lower entropy, i.e. there are some correlation between the surrounding pixels.
Based on the Matlab code by Philippe Magiera and Carl Londahl.
