| 摘 要： | 视频镜头扫换边界是一种常见的镜头边界类型,扫换的特征与大的物体/相机运动相似,比镜头的切变和溶解边界更难检测.本文提出了一种将三维的视频数据转换到二维的时空切片灰度图像,然后利用图像处理算法将扫换边界前后的镜头分割开来.本文提出的方法对大部分扫换类型有效,对扫换镜头边界的长度以及光照的变化不敏感.实验结果表明本文算法能够快速、有效地检测出镜头扫换边界.

| Abstract: | The wipe is a frequently used transitional from between shots. Wipe detection is more Involved than the detection of abrupt and other gradual transitions because e wipe may take various patterns and because of the difficulty in discriminating a wipe from object and camera motion. In this paper, we propose an algorithm for detection wipes using spatial-temporal slice. The experimental results indicate that the proposed approach is capable of detecting various wipe transitions quickly and accurately. |
