Weighted-HMM-AR-model

biometric recognition

说明：  基于s函数的神经网络PID描述。实现Matlab与simulink之间的连接。(S function of the neural network based PID description. Realize the connection between Matlab and simulink.)

均值滤波：把每个像素周围的8个像素来做均值操作，可以平滑图像，速度快，算法简单，但是无法去掉噪声，只能微弱的减弱它。(The mean filtering: 8 pixels around each pixel do mean, you can smooth image, fast and simple algorithm, but can not get rid of the noise, only faint weakened it.)

本程序是现代谱导航分析中的惯性导航中的姿态角度,东北天等信息的分析的matlab程序，经过仿真验证，获得较为准确的结果。(The navigation program is modern spectral analysis of inertial navigation in the attitude angle, northeast-day analysis of information such as the matlab program, through simulation, to obtain more accurate results.)

频率估计：Pisarenko谐波分解算法、music算法和esprit算法对有干扰的信号频率进行估计，并且计算估计频率的均值和方差。(Pisarenko、music和esprit)

就是根据隧道照明的影响因素，编写的控制策略(Is based on the impact of tunnel lighting factors, the preparation of the control strategy)

说明：  通过pq控制来调节逆变器，从而改善微电网的一些性能(The inverter is regulated by pq control, so as to improve the performance of micro-grid and make the system run more stably)

说明：  差分粒子群算法是一种新的模仿鸟类群体行为的智能优化算法，现已成为进化算法的一个新的重要分支。在基本粒子群算法和改进粒子群算法原理的基础上，实现了粒子群算法在函数优化、图像压缩和基因聚类中的应用。(Differential particle swarm optimization (DPSO) is a new intelligent optimization algorithm which imitates the behavior of bird swarm. It has become a new important branch of evolutionary algorithm. Based on the basic particle swarm optimization (PSO) algorithm and the improved principle of PSO, the application of PSO in function optimization, image compression and gene clustering is realized.)

这是一个利用水平集方法进行分割的方法，是目前使用越来越多的方法，并且有严格的数学依据(This is a level set method using segmentation method is currently used by more and more ways, and has a strict mathematical basis for)
