摘　　要：首先对基于内容的多媒体检索的相关概念、特征进行介绍,提出一种基于压缩域特征的音频检索方法,该算法在压缩域上直接对音频信号进行分析,达到多媒体实时检索的目的,实验结果证明,该算法有较好的检索结果。This paper firstly introduces the concept and characteristic of content-based multimedia, then an algorithm of content-based audio retrieval by examples is brought forward, which directly analysis the audio streaming in order to implement real-time retrieval. Experimental results indicate that this novel algorithm has better performance than others.

关 键 词：基于内容的多媒体检索 音频检索 特征提取
