Evaluation of Color Constancy Algorithms

This paper presents a review on various color constancy (CC) techniques. The CC is a method that gathers the effect of various light sources on a digital image. The scene recorded by a camera relies on three issues: the physical information of the object, the illumination incident on the scene, and the characteristics of the camera. The objective of CC is to account for the effect of the illuminate. Many existing methods such as Grey-world method, Physics based CC and Edge-based methods were used to measure the CC of objects affected by different light source. All these methods have obvious limitations that the light source across the scene is spectrally uniform. This assumption is often violated as there might be more than one light source illuminating the scene. The overall objective of this paper is to find the gaps in earlier work on CC.
