A novel image green enhancement method based on luminance and hue

This paper proposes an image green enhancement method based on luminance and hue. In the current algorithm, there are two main issues, i.e., the presence of over-saturation and color deviation, which can not satisfy people´s demands for stronger green enhancement. To solve these problems, the correct mathematical model about luminance on chrominance constraint relations is proposed and an appropriate product factor list is obtained. The MATLAB simulation images show that the proposed method effectively enhances the green color and at the same time avoid the problems of over-saturation and color deviation.
