描述了一类新的用于视频压缩的基于控制网格内插（CGI）的运动补偿方法。主要的运动补偿方法，块匹配，是CGI的一个特殊情况。提出了一种新的CGI方法，该方法产生平滑的运动矢量场，保持预测图像的连续性和连通性。与块匹配算法相比，新算法消除了块效应，同时使用相同或更少的边信息，获得近似相同的均方误差。搜索算法和编码方法以前开发的块匹配可以使用这种新技术。
A new class of motion compensation methods that are based on control grid interpolation (CGI) for use in video compression is described. The predominant motion compensation method, block matching, is shown to be a special case of CGI. A new CGI method is presented that produces a smooth motion vector field, preserving continuity and connectivity in the prediction image. When contrasted with block matching, the new algorithm eliminates blocking artifacts while using the same or less side information for approximately the same mean square error. Search algorithms and coding methods developed previously for block matching can be used with this new technique.>
