COLOR CORRECTION OF AN IMAGE WITH MULTIPLE LIGHT SOURCES USING GRAY WORLD COLOR CONSTANCY ALGORITHM

Madhuri C

Abstract :

Color constancy is the ability to estimate the color of the light source. Different color constancy algorithms are there like gray world, white patch, gray world 1st order derivative, gray world 2nd order derivative. Here, the color constancy algorithms are generally based on the assumption that the light source across the scene is uniform. But this assumption is not true in all cases. Because some images contain multiple light sources. In this paper, we consider the scenes with multiple light sources. Here we do color correction of an image with multiple light sources using gray world algorithm. Here we use local correction method.ie, we do clustering of images and apply the color constancy algorithm for each patches rather than the entire image. Color correction is done using histogram equalization method.
