Human perception inspired exposure correction using total variation model

We present the framework for the exposure correction and back-light compensation using the bilateral logarithm total variation model based on human perception called HPEC. The method aims to emulate the way in which the human visual system discriminates original color in dim light or shadow region with rod, cone and light adaptation. The proposed method is effective for appropriate illumination and vivid color restoration, suppression of artifacts such as, color distortion, HALO and noise amplification as well as automatic parameter estimation by the image statistics analysis.
