Method for extracting wavelet characteristic based on blur wavelet bag disintegrating

, 2008
本发明属于信号处理和模式识别技术,具体公开一种基于模糊小波包分解的小波特征提取方法,取平稳信号或非平稳信号为信号样本,包括对已标明类别的信号样本的训练过程和新未知类别的信号样本的特征提取过程,以训练过程为主体;即通过训练过程找最优小波分解Ω*;以最优小波分解Ω*为基础,提取鉴别能力强的小波系数特征;在新未知类别样本的特征提取过程中提取已定位的小波系数作为最终特征。采用本发明对平稳或非平稳信号(包括剧烈变化信号)进行处理,提取出鉴别力强的小波系数特征,使同类信号的类内距尽量小 ...
