PROCEDE D'ESTIMATION DU MOUVEMENT BIDIRECTIONNEL ET DISPOSITIF CORRESPONDANT |
摘要 |
<p>A bi-directional motion estimation method and apparatus thereof in a low bit-rate moving video codec system, for filtering motion vectors by performing a bi-directional motion estimation in units of objects having the same motion in a constant domain and for compensating the motion using the motion vectors generated as the result of forward or backward motion prediction in accordance with the motion prediction mode of previously set frames, can determine the precise motion vector compared to the existing block matching algorithm and depict the inter-frame motion with a smaller amount of information. Therefore, markedly less data (for compression) is used and reconstructed picture quality is improved.</p> |
