| 摘 要： | 镜头边界检测是实现基于内容的视频检索的一个重要步骤.文中介绍了现有的镜头边界检测的基本方法,并针对其不足提出了一种自动选取阈值的、综合考虑颜色和空间特征的镜头边界检测算法.该方法能较好地检测出镜头突变和物体运动以及光线变化等情况,对渐变镜头也能达到检测的目的.实验结果表明算法能够有效地检测出视频镜头边界.

| Abstract: | An important step in content-based video retrieval is the temporal segmentation of video.We give an overview of some existing shot boundary detection algorithms.After that,we propose an algorithm for shot boundary detection that integrates the spatial and color features of frames.Our method is not sensitive to brightness change and quick motion.Therefore,it can improve the precision of detecting shot boundaries.Finally we give the experimental results and draw the conclusion. |
