摘要：Color Constancy is the capability to recognize colors of objects, invariant to the color of the illumination source. This ability is usually endorsed to the Human Visual System, even though the precise details remain hesitant. Visual surveillance is one of the applications of color constancy which aims to improve the reliability of applications that depend on consistent color descriptions. Also Image enhancement plays a substantial role in vision based applications. Recently significant work is done in the field of digital image enhancement. Many techniques have been proposed up to now for enhancing the poor quality or low intensity images. It has been discovered that a lot of the active techniques are based on the transform domain methods which might introduce the color artifacts and also might decrease the intensity of the already enhanced image. The overall objective of this paper is to review various image enhancement and color constancy techniques. This paper also defines the scope of color constancy in the image enhancement.
