AbstractColour is an important clue in many applications in machine vision and image processing. Despite of this, the drwback of color is its dependence upon illumination changes. Coluor constrancy aims to provide colur appearence of objects with stability. This paper presents a simple and robust coluor constrancy algorithm based on a coefficient transformation of the colour coordinates of pixels which goal is to reduce the distance between histograms of two images of similar scenes under different illuminations. Our main contribution is that our algorithm only make use of raw image data contrary to most usual coluor constancy algorithms. We show that our approach is able to cope with the colour change since it substantially reduces the distance between colour histograms.
