一个简单的只需定义函数，参数范围即能求解的粒子群优化算法(Just a simple definition of function, which can solve the parameters of the particle swarm optimization algorithm)

说明：  matlab 对基于形状的图像检索的算法 其中以七个不变矩为主要方法！！！！！！(matlab shape-based image retrieval algorithm for which the seven invariant moments as the main method! ! ! ! ! !)

retinal blood vessel processing different angles or different orientation

the simulation provides computation of target reflectivity data in the deficient elevation domain. Simulations are implemented to test the decoupled least-squares technique for high resolutionspectral estimation of target reflectivity.all seven (7)files should be downloaded for the simulation to work.(dls3D.m,estimate.m,get2S1Data.m,getConstraints.m, getImageData.m,getPixelData.m, getSLICYData.m)

说明：  学习自适应天线，RLS最常见一种算法，这里提供其编程思路，供参考(Learning adaptive antenna, RLS algorithm is the most common kind, which offers its programming ideas, for reference)

基于GMM的说话人识别程序，提取梅尔倒谱特征进行训练(voice detection based on GMM)

图像检测标定的方法测量海绵的位移量，附多幅实拍图像(Calibration image detection method for measuring the displacement amount of the sponge，attached pieces of real film images)

使用matlab对给定的图像进行提取rgb颜色特征，并输出颜色直方图(use matlab to extract the rgb feature )

使用matlab对基于最小错误率的Bayes分类器进行仿真，编写了相应的程序，分为协方差相等和不相等两种情况，最后画出了三类的分界线(Using matlab to the smallest error rate based on the Bayes classifier to carry out simulation, the preparation of the corresponding procedures, divided into equal covariance and unequal both cases, the final draw of the three types of line)
