In this paper, we propose to introduce intrinsic image decomposition priors into decomposition models for contrast enhancement. Since image decomposition is a highly ill-posed problem, we introduce constraints on both reflectance and illumination layers to yield a highly reliable solution. We regularize the reflectance layer to be piecewise constant by introducing a weighted $\ell _{1}$ norm constraint on neighboring pixels according to the color similarity, so that the decomposed reflectance… CONTINUE READING
