Compact motion representation based on global features for semantic image sequence coding
Claude Labit, Henri Nicolas · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1991
For dynamic scene analysis [HOR81],[ADI85],[HAR85], numerous studies developped derivation methods of qualitative motion features from a dense apparent velocity vector field (optical flow). However, these qualitative information [FRA90] can not be used for image sequence reconstruction because no explicit reconstruction criterion is introduced within the feature identification process itself.
