Method of estimating backward motion vectors within a video sequence |
摘要 |
A method of speeding the computation of backward motion vector estimates which are derived from fields which are available from forward motion vector estimates as based on nearest neighbor criterion. The method allows for the generation of multi-frame backwards motion vectors. The invention of the present method for estimating backward motion vectors is particularly well-suited for use with the MPEG-2 video standard. |
