%   Distribution code Version 1.0 -- 09/23/2011 by Jiaya Jia Copyright 2011, The Chinese University of Hong Kong.
%
%   The Code is created based on the method described in the following paper
%   [1] "Image Smoothing via L0 Gradient Minimization", Li Xu, Cewu Lu, Yi Xu, Jiaya Jia, ACM Transactions on Graphics,
%   (SIGGRAPH Asia 2011), 2011.

function S = L0Smoothing(Im, lambda, kappa)
%L0Smooth - Image Smoothing via L0 Gradient Minimization
%   S = L0Smoothing(Im, lambda, kappa) performs L0 graidient smoothing of input
%   image Im, with smoothness weight lambda and rate kappa.
%
%   Paras:
%   @Im    : Input UINT8 image, both grayscale and color images are acceptable.
%   @lambda: Smoothing parameter controlling the degree of smooth. (See [1])
%            Typically it is within the range [1e-3, 1e-1], 2e-2 by default.
