NIGHT IMAGE ENHANCEMENT USING FUSION TECHNIQUE

Amritpal Singh, Vijay Kumar Banga

Abstract: Video surveillance is used in monitoring the road traffic. However because the surveillance system is limited by many objective factors. Surveillance video may not be seen clearly. Especially under the weak light conditions, the picture quality of the night video is very poor. In this paper, we propose an enhancement method of nighttime images for surveillance camera. We apply the moving target extraction technology and illumination estimation theory and combine the nighttime image with the daytime background by the image fusion. The proposed method recoveries scene information of the night video and highlights the details. The resultant images show the vehicles of the night time but surrounding is fused from the day image taken at day. In this, it is observed that the PSNR value is 65.9 dB is very high and MSE is 0.128 which is very low as compared with earlier reported night image enhancement technique [1]. Experimental results prove that our method is effective
