rgb2lab() Converte de RGB image to para LAB, a LAB2RGB Convert an image from CIELAB to RGB.

都是关于空间普估计算法，其中有解相干和非相干算法以及它们之间的对比( the spatial spectrum estimation)

粒子群算法，本算法对粒子群算法进行了改进(PSO, the PSO algorithm has been improved)

matlab程序，一种快速ICA算法，用于混合信号盲分离，可应用于通信系统信号处理(matlab program, a fast ICA algorithm for blind separation of mixed signals, signal processing can be used in communication systems)

自相关虽然能够判断清/浊音，并估计浊音的基音周期，但是其运算量很大，用乘法运算所需时间较长。为了避免乘法，采用短时平均幅度差函数（AMDF），验证AMDF与自相关有类似的作用，即平均幅度差函数能够代替自相关函数进行语音分析。(Although autocorrelation can differ from the Voiced/Unvoiced and voiced the pitch period estimate, but the operation is large enough, with the multiplication time was needed. In order to avoid the multiplication using the short time average magnitude difference function (AMDF), verify the AMDF and autocorrelation have a similar effect, that the average magnitude difference function can replace the voice of the autocorrelation function.)

参数估计，最大似染发、最小二乘法，Monte_Carlo法仿真10000点 (Parameter estimation, maximum likelihood hair, least square method, Monte_Carlo 10,000 points for Simulation)

说明：  dsp相关的matlab程序，有很多哦， 很有用的(dsp procedures related to the Matlab, many Oh, very useful)

说明：  时间序列的自回归预测模型，是一个利用前期若干时刻的随机变量的线性组合来描述以后某时刻随机变量的线性回归模型(The autoregressive prediction model of time series is a linear regression model that describes random variables at a later time by using the linear combination of random variables at some earlier time.)

指纹图像特征提取，采用matlab编程实现(Fingerprint image feature extraction, using matlab programming)
