Generalized histogram and its application in color image enhancement

The generalized histogram is constructed and applied in color image enhancement by histogram equalization.To consider that classical histogram equalization method has not universal suitability properties in color image enhancement,classical histogram of gray image is firstly modified to obtain a generalized histogram of gray image,then color image is enhanced by the generalized histogram equalization in HSV color space.Some experimental results show that the color image enhancement method proposed in this paper is feasible,and much better effect than that of classical histogram equalization.
