摘要

针对网络海量数据的应用特点

对传统的直方图算法进行了改进

采用基于主轴树的快速矢量量化技术进行预处理

采用两阶段法进行搜索处理

实验结果表明这2种方法可以显著提高检索的速度和精度。

Abstract

According to the characteristic of network massive data

the traditional histogram algorithm was improved.The principle axis search tree is utilized for pre-processing and the two-stage method is presented for audio retrieval.Ex-perimental results show that the two proposed methods can significantly improve the search speed and precision.
