This filter performs total-variation denoising using split-Bregman optimization [1],[2],[3],[4] , from the scikit package. In general, images with excess noise have high total variation, i.e the magnitude of the gradient is high. This filter focus on split Bregman algorithm to remove unwanted detail whilst preserving important details by reducing the total variation of the noisy input.
