ImfAnalysis
- 关于希尔伯特黄变换(HHT)中最重要的概念即本征模态函数(IMF)的程序,初学者可利用该程序对任意信号进行分解,加强对HHT的理解。-For the Hilbert-Huang Transform (HHT) the most important concept that the intrinsic mode function (IMF) procedures, beginners can use the program to decompose the arbitrary signal, to
emd
- 经验模态分解程序包 希尔伯特黄变换程序的matlab程序仅供参考(Empirical mode decomposition package Hilbert Huang transform program)
decomposition
- 运行emd,得到输入信号X的固有模态函数(imf),每列代表着信号X的一阶分量,X就是我们采集的信号。 hhtdn是hht去噪的程序,可以不看,仅看emd 和 findpeaks wvtdn是wavelet去噪程序,如果只是分解信号,仅用下面的语句即可 [C,L] = wavedec(x_noise,dl,wn); x_noise就是我们采集的信号,dl是分解的阶数,wn是分解的母小波名称(% Empiricial Mode Decomposition (Hilbert-Huang
EMDs
- 经验模态分解程序,分解出各本征模函数。直至剩余部分变为不含任何模式信息的单调序列即余项。(The empirical mode decomposition program decomposes the eigenmode functions. Until the rest part becomes a monotone sequence that does not contain any pattern information, that is the remainder.)
bemd
- 二维EMD程序,这是利用最新的插值函数,个比较经典的二维经验模式分解程序代码,适用于图像的特征提取和分解((A two-dimensional EMD algorithm, the author is Anna Linderhed, her Ph.D. research topic is bidimensional EMD and wavelet transform))
