Abstract

A new hybrid image enhancement approach based on the parameter-controlled virtual histogram distribution method can enhance simultaneously the overall contrast and the sharpness of an image. The approach also increases the visibility of specified portions or aspects of the image whilst better maintaining image color. It driven by both global and local processes on luminance and chrominance components of the image. The approach was compared with other well-known image enhancement techniques. The experimental results have shown the superiority of the proposed approach
