拟牛顿法matlab程序

阈值法实现灰度图像分割，效果不错，可行，可以借鉴(Threshold method to achieve gray-scale image segmentation, the effect of a good, viable, can learn from)

高阶容积卡尔曼滤波程序，CKF，可用于滤波和跟踪(using high-degree Cubature Kalman filters)

添加噪声处理，基于人工神经网络的常用数字信号调制，包括单边带、双边带、载波抑制及四倍频,是国外的成品模型，D-S证据理论数据融合，利用matlab GUI实现的串口编程例子。

One of Biometrics fields is face recognition & face expression recognition ... 1- In face recognition .. we need to design authentication program by training a neural network ,there are two source codes..one of them is based on Discrete Wavelet Transform with Perceptron Neural Network.. and the other based on Discrete Cosine Transform with Perceptron Neural Network ... 2- In face expression recognition .. we defined the condition of the person (nature,happiness,disgust or anger) this source code is based on Principle component analysis(PCA) .. * we need to now about digital image processing ,neural network and PCA...

Floyd算法,对研究通信网性能分析很有帮助(Floyd algorithm, the study of communication network performance analysis very helpful)

说明：  matlab开发的粒子滤波目标跟踪程序，跟踪目标良好。(Matlab development of particle filtering procedures。)

对hurst指数估计，本人已经做过测试，是正确的，下载可以直接使用(the estimation of hurst for time series！)

导航，定位，公交线路查询，到站提醒，周边搜索等服务。(Navigation, positioning, bus lines inquiry, the station remind surrounding search and other services.)

A vocoder is an analysis/synthesis system, mostly used for speech. It is a simple vocoder that uses auto-correlation method to estimate the pitch.
