Morlet离散小波变换(Discrete Morlet Wavelet Transform,DMWT)是一种基于小波分析的信号处理方法,用于分析和处理非平稳信号。它是由小波函数Morlet小波(Morlet wavelet)构成的小波变换方法。Morlet小波是一种连续小波,经过离散化处理后可以应用于离散信号的分析。 Morlet小波是由高斯函数和复指数函数(调制信号)相乘得到的复...
Subsequently, the detailed dynamic test of the modal structure and the study of the applicability of modal identification using Morlet wavelet transform are carried out. Besides, some improvements are suggested to the modal identification using Morlet wavelet transform, which are verified by a modal ...
Self-adaptive Wavelet-ridge Extraction Algorithm Based on Morlet Wavelet Transform LI Cong,LI Wei PDF 716 被引次数 1 摘要/Abstract 摘要: 传统小波脊线提取算法在不同信号环境下选择小波参数较为困难。为此,提出一种针对Morlet小波变换谱自适应提取小波脊线的算法。通过分析小波脊线算法,以迭代运算的成功...
Morlet continuous wavelet transform (MCWT) has been widely used to process non-stationary electro-encephalogram (EEG) data. Nowadays, the MCWT application for processing EEG data is time-sensitive and data-intensive due to quickly increasing problem domain sizes and advancing experimental techniques....

[1] The normal Morlet wavelet transform (NMWT), which is a mathematical method for harmonic analysis, is defined in this study by resorting to L1 normalization continuous wavelet transform and a normalized simplified Morlet wavelet. The NMWT of a complex time signal enables direct recognition and...
wavelet_transform函数对信号进行卷积,从而得到小波变换的结果。 最后部分生成了一段示例信号,调用小波变换函数,并通过matplotlib可视化原始信号和变换结果。 类图 在实现过程中,我们可以将Morlet小波分析看做一个类,下面是其类图: MorletWavelet+morlet_wavelet(t: array, sigma: float, omega_0: float)+wavelet_transfo...
