摘要
水声音符识别在水声数据库检索技术中有很重要的应用价值,但目前还没有比较成熟的水声音符识别方法。本文通过深入研究水声的物理特性和音乐特性,提出一种识别水声音符的方法,该方法实现在水声频域的精确定位,该方法主要研究目的在于使计算机听懂水声并对其自动进行编译,形成水声数据库,在水声识别中有很重要的实用价值。
Underwater acoustic note recognition has very important application value in the technology of underwater acoustic database retrieval, but there is no mature method for the recognition of underwater acoustic notes. Through in-depth study of underwater acoustic physical characteristics and features of music in this thesis a recognition of underwater acoustic note method, this method realized in the precise positioning of underwater acoustic frequency and achieved better recognition effect, has certain application value.
