Research on adaptive histogram modification algorithm for color image

In order to overcome image detail lossing, distortion and over-enhancement caused by histogram equalization, a novel algorithm for color image enhancment based on adaptive histogram modification is proposed. According to the distribution of gray-scale, the algorithm will construct the target gray sequence, choose the right mapping mode, and adaptively modify the image after histogram equalization base on gray mapping. An adaptive judgment method and flow of gray mapping is also designed. The experiments show that the algorithm can not only effectively overcome the over-enhancement and distortion, restoration the image partial detail but also improve the images' color to be more vivid and lively. The effect of color image enhancement is remarkable.
