摘　　要：视频检索要求在大量的视频数据中找到所需要的视频片断。运动分析的目的是恢复对象的结构和识别移动对象。运动分析的过程分为三个阶段:移动对象的检测,通过确定的运动特性来跟踪对象,以及运动特征的最终集成。介绍了基于ST表面流和ST流曲线的运动分析方法,综合运动分析的三要点完成了专业篮球运动员的投篮动作与一位普通小女孩的投掷动作的区分。Content-based retrieval of digital video requires to find out the video segments required in the amount of video data. The goal of motion analysis is to retrieve the structure of an object and to recognize the moving object. The process of motion analysis is consisted three steps:examining the moving object; tracing the object by the determined motion characteristic, and summarizing the motion characteristics finally. The motion analysis based on ST surface flow and ST flow curves is introduced, and the analysis of a professional hoopster and a lassock's throwing ball motions and its difference are performed.

关 键 词：视频检索 运动分析 ST表面流 ST流曲线
