Gray world algorithm python

WebAbstract. In this paper, the estimation of the illuminant in color constancy issues is analysed in two perceptual color spaces, and a variation of a well-known methodology is presented. Such approach is based on the Gray-World assumption, here particularly applied on the chromatic components in the CIELAB and CIELUV color spaces. WebIn this paper, we propose an improved algorithm based on Salient Detection to achieve Color Constancy, which can cover the aforementioned shortage of the Gray World algorithm. The extensive validation of our method on commonly used dataset which includes images under varying illumination conditions is presented.
