An effective method for night time video enhancement

In this paper, an effective method combining histogram manipulation and moving objects region enhancement for nighttime video enhancement is proposed. The proposed method firstly extracts moving objects region from a video image. Secondly the RGB color space of video is converted to YCbCr color space. Thirdly Y component is enhanced using histogram manipulation. In order to improve the perceptual quality of the moving objects region, we propose a moving objects region enhancement method. Finally color image is reconstructed. Experimental results show that our method can obtain more appealing perceptual quality than the state-of-the-art algorithms. The experiment shows the effectiveness and robustness of the proposed method.
