| 摘 要： | 基于实时视频图像序列的运动矢量分布特性,本文提出了一种新型的混合模式运动估计搜索(MPS)策略。该算法根据给定的搜索距确定相应的搜索模式,使用中途停止技术快速的给出运动矢量。相比现有各种搜索算法,MPS搜索策略能够同时满足图像序列中的高速运动与慢速运动的搜索。仿真试验表明,本文搜索策略不仅在搜索速度上比现有MPEG-4校验模型的DS算法更加快速,并且具有更小的运动补偿误差以及更加真实的运动矢量场。

| Abstract: | Based on the real video image sequence's characteristic of motion vector distribution,a novel mixture pattern motion estimation search scheme is proposed in this paper.Motion vector is obtained by halfway-stop technique and search pattern which is confirmed by the search distance.Compared with various search schemes,MPS can satisfy the high speed search and slow moving search simultaneity in video image sequence.The experimental results show that is estimated by novel scheme not only faster than the DS algorithm which is MPEG-4 VM,but also has much less motion compensation error and more genuine motion field. |
