【摘要】 针对小波变换工程应用软件开发需要,结合Mallat算法原理分析介绍了离散小波变换的主要功能步骤以及程序设计技术的关键问题。算法采用Delphi语言实现,大量数据验算表明,程序运算中间及最终结果和用Matlab小波工具箱编写的小波变换程序执行情况完全一致。主要算法均以子函数形式给出,便于研究人员把在Matlab中开发的小波变换应用算法成果转化为其它高级语言程序,构建独立的专用软件系统。更多还原

【Abstract】 For the application software development of wavelet transform(WT),some key steps and techniques for programming are introduced based on Mallat algorithm analysis and descriptions.Many data are employed to check the proposed algorithm programmed by the language of Delphi.The interval and final results shows no differences from the outputs produced by WT programs with the Matlab wavelet toolbox.The main algorithms are written as sub-functions that are helpful for the researchers to convert their achievements in Matlab to other computer languages and construct the WT software for specialized application independently.更多还原
