try this first to do image segmentation for you. Its very easy to follow.

EasyMod is a MatLab/Scilab toolbox for teaching modal analysis. It provides a set of functions allowing to establish the identification of modal parameters and these validation. Nowadays, circle-fit, line-fit and least square complex exponential methods are implemented. In addition, some relevant functions are offered in order to complete a modal analysis: operations on the frequency response function (FRF) , generation of FRF from mass, damping and stiffness matrices, MAC (modal assurance criterion) and modal collinearity

Sigma_delta调制器的matlab模型和完整代码，可通过仿真观察输入输出信号波形以及输出的频谱，最后还说明了如何计算信噪比(Sigma_delta modulator of matlab models and complete code, can observe the simulation input/output signal waveform and the output spectrum, finally also illustrates how to calculate the SNR)

实现串口的数据采集，信号维数的估计，可以实现模式识别领域的数据的分类及回归。( Achieve serial data acquisition, Signal dimension estimates, You can achieve data classification and regression pattern recognition.)

说明：  ％极大似然方法 gcn为高斯有色噪声！！！比较不同点( Maximum likelihood method for Gaussian colored noise GCN! ! ! Compare different points)

Time Series Forecast With Neural Network and Wavelet Techniques

本程序通过优化ICA算法实现了混合图像的盲源分离，分离效果优于一般ICA算法(This procedure optimized ICA algorithm is a mixed picture of blind source separation, separation is better than the general ICA algorithm is)

As digital computers cannot generate true random numbers. So a pseudo random number generator must have uncorrelated sequences, long period, uniformity and efficiency. ‘myrand.m’ has pass the chi square test for uniform distribution.

处理质谱曲线warping的一个GUI程序，很不错-MS treatment warping curve a GUI program, it is good(a GUI to deal with mass spectrometry figure )

说明：  最优制导律攻击机动目标弹道仿真，matlab编写。(Optimal guidance law for maneuvering target trajectory simulation attacks, matlab prepared.)
