中文百科
运动补偿运动补偿是一种描述相邻帧(相邻在这里表示在编码关系上相邻,在播放顺序上两帧未必相邻)差别的方法,具体来说是描述前面一帧(相邻在这里表示在编码关系上的前面,在播放顺序上未必在当前帧前面)的每个小块怎样移动到当前帧中的某个位置去。这种方法经常被视频压缩/视频编解码器用来减少视频串行中的时域冗余。它也可以用来进行去交织(deinterlacing)以及运动插值(motion interpolation)的操作。 一个视频串行包含一定数量的图片--通常称为帧(frame)。相邻的图片通常很相似,也就是说,包含了很多冗余。使用运动补偿的目的是通过消除这种冗余,来提高压缩比。
英语百科
Motion compensation 运动补偿![]() Motion compensation is an algorithmic technique used to predict a frame in a video, given the previous and/or future frames by accounting for motion of the camera and/or objects in the video. It is employed in the encoding of video data for video compression, for example in the generation of MPEG-2 files. Motion compensation describes a picture in terms of the transformation of a reference picture to the current picture. The reference picture may be previous in time or even from the future. When images can be accurately synthesised from previously transmitted/stored images, the compression efficiency can be improved. |
