提出了一种基于样本的分级检索 MPEG 视频的新方法:首先用I 帧的dct_dc_size 字段快速粗检,然后用断层摄影(tomography)法分析B 帧运动矢 量的时空分布特性以进一步缩小结果集,最后用DC 图像的精确匹配方法验证检索结果.试验结果表明,本方法 所需计算量较小,且可保证较高的检索精度.-presents a sample classification based on MPEG video retrieval of the new method : First of all I frame with the rapid field dct_dc_size rough Frederick, and then use tomography (tomography) Analysis of B pictures motion vector space-time distribution to further narrow the results set, and DC Images precision Matching test results retrieval. test results showed that the calculation method for small and can guarantee higher retrieval accuracy.
