Global motion estimation–based method for nighttime video enhancement

In order to efficiently enhance the dark nighttime videos, the high-quality daytime information of the same scene is often introduced to help the enhancement. However, due to camera motion, the introduced daytime may not have exactly the same scene of the nighttime videos. Thus, the final fused moving objects may not produce reasonable results. In this paper, we make the following two contributions: 1. we propose a global motion estimation-based scheme to address the problem of scene differences between daytime and nighttime videos. 2. Based on this, we further propose an improved framework for nighttime video enhancement which can efficiently recover the unreasonable enhancement results due to scene differences. Experimental results show the effectiveness of the proposed algorithm. C 2011 Society of Photo-Optical Instrumentation Engineers (SPIE).

“…The bright pixel level of the night video is less compared to daytime video. So context enhancement based fusion is required to provide a better visual perception in the night video enhancement [2], [3], [7]. A surveillance security system consists of video data captured under different illumination conditions.…”

“…A surveillance security system consists of video data captured under different illumination conditions. The context enhancement scheme utilizes the features of the video captured during the bright light condition [2], [3], [7]. The visual performance of this enhanced video is insufficient to interpret the meaningful information due to its false color distribution.…”

A dark video captured during night surveillance is insufficient to recognize an action. In order to perform various video analysis operations, a night time video enhancement approach is required. A daytime coloring approach is proposed to improve the visual perception of night video. The day image is down sampled and its color features are applied to the night fusion video. The experimental results are compared with context enhancement fusion methods and objective metrics are used to evaluate the performance of the algorithm. The quality measures show that edge pixel strength and contrast of the surveillance videos are enhanced compared to other methods.
