Hurlbert Regularization
Test 5

These images are the result of filtering with a Hurlbert regularization filter, then biasing to gray. A relaxation was then applied, taking into account edges in luminance to constrain the color diffusion within regions belonging to a single surface.

Two dimensional histograms of the computed images are available: chromaticity and Red vs. Blue
