基于时空切片的球拍类体育视频比赛镜头抽取

Extract playing shots for racket sports video using spatio-temporal slice

提出了一种基于短时切片的球拍类体育视频比赛镜头提取方法。该方法对视频时空切片分帧,通过对切片帧聚类、合并、边界检测和映射获取比赛镜头。实验表明该方法具有很好的鲁棒性和准确度。

A novel method based on spatio-temporal slice is proposed to extract playing shots for racket sports video.The method divides video spatio-temporal slice into frames,and uses methods including clustering,merging,boundary detection and projection to obtain playing shots.Experiments demonstrate that the method is accurate and robust.
