The linear weighted average method is adopted to integrate the results of different scale Retinex Algorithms,but it did not stress the merit of each scale in maintaining the details and the color fidelity effectively.So a novel Multi-Scale Retinex Algorithm is proposed in this paper.It segments original image into four illuminance regions by involving the parameterized LIP model.Then each region is enhanced by Retinex Algorithm whose scale is selected according to the illuminance difference.At last,based on...
