A back lighting color image enhancement method using color saturation and image fusion

In this paper, a back lighting color image enhancement method using color saturation and image fusion is presented. First, the saturation component of color image is computed by using HSV or HSI color space. Then, two different exposed images are generated by using weighting function method. Next, the enhanced image is obtained by fusing input color image and two different exposed images. Finally, several numerical examples are demonstrated to show the effectiveness of the proposed enhancement method.
