摘要
根据对视频时空切片的分析,提出了一种从视频中提取摄像机运动特征的方法:通过镜头突变检测,将视频分割为单镜头序列,再检测镜头中摄像机的运动。实验证明,该方法是鲁棒且有效的。
According to the analysis of video spatio-temporal slices, we propose a novel algorithm to detect camera motion in videos. In this paper, we first segment the video into some single-shot-sequences, then analyze camera motion in these sequences. Some experimental results show the method is effectual and robust.
