- 正交EMD的MATLAB程序 用以改進IMF的正交性質-Orthogonal EMD MATLAB program for the improvement of the orthogonal nature of the IMF
emd
- 对于输入的时间序列，按照经验模式分解得到一系列基本模式分量和余项的和。经验模式分解是区别于傅里叶变换和小波变化的一种更一般的时间序列频率分解的方法- IMF = EMD(X) where X is a complex vector computes Bivariate Empirical Mode Decomposition of X, resulting in a matrix IMF containing 1 IMF per row, the last one being the

- HHT（Hilbert-Huang）变换的IMF分解程序，为matlab编译的C++代码，需Matlab2010环境支持，或者安装相应的MCRInstaller。vc配置请查阅matlab和vc混合编程知识。-HHT (Hilbert-Huang,) transform the IMF decomposition procedure, Matlab compiled C++ code required Matlab2010 environment support, or install the
HHT-emd
- MATLAB的EMD工具箱，主要是对信号进行IMF分解，然后进行希尔伯特变换。得到信号的瞬时频率，并画出能量图。 使用是解压到matlab的work里面即可。-MATLAB toolbox of EMD, decomposition IMF, then Hilbert transform signal. The instantaneous frequency of the signal, and draw the energy diagram. Use extract to matlab c

- Java版本的EMD分解程序，可利用Chart.java显示IMF,边际谱，瞬时频率，亲测-Emperical mode decompsition Hilbert transform Jfreechart
EMDdenoise
- 一种基于EMD分解后对imf分量利用小波分解进行去噪的方法，给出了相应的例子，有注释-Based on the EMD decomposition after the imf component by using the method of wavelet decomposition denoising, corresponding examples are given, with comments
bemd
- Descr iption: The function is called upon as follows: a = bemd(im1) im1 -> Image a(:,:,1) => IMF 1 a(:,:,2) => IMF 2 a(:,:,3) => IMF 3 a(:,:,4) => Residu
