摘要
为了提高低照度视频的视觉效果,提出一种基于对数图像处理(LIP)的增强算法和改进的双向均衡算法相结合的方法,并运用帧间互相关信息,在保证视觉效果的前提下,减少了处理的帧数,提高了处理的速度。实验结果表明,该方法简单、实用,能够得到较理想的效果。
In order to improve the visual effect of low illumination video, a hybrid algorithm was proposed, which included the Logarithmic Image Processing （LIP）-based enhancement algorithm and the improved hi-direction balancing algorithm. The number of processing frames was reduced by using the inter-frame cross-correlation to improve the processing speed. Experimental resuhs show that the proposed algorithm can obtain more satisfactory results.
