摘要
从视频检索技术的发展背景出发,重点介绍了视频检索技术中镜头的边界检测技术。分别介绍了基于解压的全图像序列的算法,基于压缩视频的算法以及基于确定变换模型的算法三类算法。最后,对基于内容的视频检索提出一些值得进一步研究的问题。
This article started from the development background of video retrieval technology, focused on the shot boundary detection technology of video retrieval. It introduced the algorithm based on the decompressed entire image sequence, the algorithm based on the compressed video and the algorithm based on established transform model. Finally, it advanced some further studies for the content-based video retrieval.
