摘要
文章提出了一个基于内容的视频检索系统模型,该模型直接对压缩视频数据进行处理,可节约解压缩的时间,减少运算量,提高系统处理效率。文章对该模型的系统结构以及系统实现所需的一些关键技术进行了介绍。
A model of content-based video retrieval system on the compressed domain is presented.By performing minimal decoding on compressed data,computational complexity is reduced,and the processing speed can be dramatically improved.The architecture and structure of the content-based video retrieval system is discussed firstly,then the principles and methods of key technologies used in the content-based video retrieval system are described.
