Video Denoising with Undoing for Hybrid Video Coding
本发明提供一种恢复噪声的视频编解码方法,包括:在编码端执行去除噪声的视频编码方法;在解码端执行恢复噪声的视频解码方法。在去噪处理中,对有噪残差信号或者其变换系数进行缩放与平移,以得到当前帧的真实视频信号的最优估计信号与其参考帧之间的残差信号,然后对该残差信号进行变换、量化和熵编码,组成压缩码流以供输出。在恢复噪声处理中,对重构的残差信号进行反缩放与反平移,以得到恢复的有噪残差信号,并将得到的有噪残差信号与当前帧的参考帧相加得到噪声恢复的视频信号。相应地,提供一种恢复噪声的视频编解码系统。本发明可恢复原始的真实噪声,引入的额外负担小,去噪处理和噪声恢复处理可容易地集成到标准视频编解码系统中。
