摘要 小波技术是对信号进行处理的重要工具,已广泛应用于信号分析、数据压缩和降噪等各个领域。该文从模式识别的角度,对各种小波变换特征构造与选择进行了全面的分析比较,探讨了各自作为模式特征对分类精度的影响,并着重对小波系数的平移不变问题和小波基的选择问题进行了详细的讨论。 Wavelet transform is important for signal analysis,and has been used in many fields such as signal analysis,data compression and denoising.This paper overviews all possible features based on wavelet transform,and discusses two basic problems of wavelet basis selection and the solutions to deficiency of shift-variant for discrete wavelet transform.
