摘要
随着数据库技术、多媒体技术、网络通信技术和信息压缩技术等的不断发展,各项指标提取的准确性进一步提高,使之基于内容的视频检索效率也将得到进一步的提高。阐述了基于内容的视频检索过程和关键技术,并通过Autonomy和OpenV两个实例来分析基于内容的视频检索技术的应用情况。
With the development of database technology,multimedia technology,network communications technology,and information compression technology,etc.,the accuracy of each indicator has enhanced,which increases the efficiency of content-based video retrieval.This paper elaborates the process and key technologies of content-based video retrieval,and analyzes the application of content-based video retrieval technology by using two examples of AUTONOMY and OpenV.
