階層的動き推定とその滑らかさを考慮したフレーム内挿 : 画像通信システム : 画像応用

In this paper, we propose a frame-interpolation algorithm considering the smoothness of the motion of moving objects. In our proposal, motion field is estimated by a hierarchical block matching scheme, in which motion field is corrected by using information about appearing regions, occluding regions, and edge points. Frames are interpolated in such a way that the displacement of the moving objects between frames is approximated with the cubic-spline function.
