Color Enhancement in the Wavelet Domain


Color enhancement

How to use this demo

This demo implements the algorithm introduced in the paper A Wavelet Perspective on Variational Perceptually-Inspired Color Enhancement published in 2014 by E Provenzi and V Caselles. This algorithm performs color and contrast enhancement in the wavelet domain and this demo allows you to test it on your own images. Note that image larger than 1200x1200 are resized to avoid too long computation time and/or mermory consumption.


The Stretch dynamic selector allows to expand the image dynamic after algorithm processing. The stretching can be done either on the luminance channel or oon each RGB channel independently.


The best way to understand then is with any doubt to read the paper, but i provide some hint to build intuition on their effects.
