| 摘 要： | 论述了几种基于时域和空域混合的对低信噪比视频图像进行降噪处理的算法.考虑单独使用时域或空域降噪算法对视频图像进行处理的缺点和不足.在时域上,由于视频图像帧与帧之间有较强的相关性,采用递归加权算法;在空域上,分别采用第二代Curvelet变换理论的Wrap算法( Wrapping-Based Transform)、全变差...

| Abstract: | This paper presents several mixture methods based on temporal domain and spatial domain of low SNR video denoising algorithms.The new methods take into account separately the insufficiency of temporal domain or spatial domain video denoising algorithm.In temporal domain,there is a strong link between video image frames and frames,so we adopt the recursive weighting algorithm.In spatial domain,we adopt Curvelet Transform theory of second generation algorithm(Wrap Wrapping-Based Transform),Total Variation(TV)... |
