ColorConstancy

The goal of color constancy methods is to transform the colors of an image I, acquired under an unknown light source, so that they appear identical to colors under a canonical light source. This task is accomplished by performing two separate steps: estimation of the color of the light source in RGB coordinates, e = [eR eG eB] T , and transformation of the image using the estimated illuminant
