Paper Abstract

A simple method for enhancing low-contrast gray image is proposed. The method decomposes an image into the layers of illuminance and reflectance, by using an edge-preserving low-pass filter, and separately enhances each layer. Finally, the enhanced results of these two layers are recomposed as the output. Experiment shows the good results on real images.
