A Fast Video Illumination Enhancement Method Based on Simplified VEC Model
Yadong Wu, Yu Sun, Hongying Zhang · Procedia Engineering · 2012
The video enhancement is necessary and needed in computer vision and many applications, especially in low illumination environment. In this paper, a fast video enhancement method based on simplified VEC (Virtual Exposure Camera) model is proposed to enhance dim videos. The proposed enhancement method mainly includes two parts. One part is the video filters that we used in pre and post video processing to reduce noise. The other part is tone mapping used to adjust video illumination. Experimental results show that the proposed method is effective in real time video processing, and results in satisfied results for low exposure video.
