Title:
ビデオシーケンス内における後方動きベクトルの推定方法
Document Type and Number:
Japanese Patent JP4394958
Kind Code:
B2
Abstract:
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.
