Enhancement technique for uniformly and non-uniformly illuminated dark images

Recently, considerable research has been done to reduce the gap between direct observation of a scene and its recorded image. Typically the differences exist because of the high dynamic range compression capability of the human visual systems, and its capacity for color constancy. In this paper we define a new method that provides dynamic range compression, color consistency and color rendition for dark images with uniform and non-uniform illumination.
