基于灰度投影的人脸特征定位--matlab(Based on gray-scale projection of facial feature location- matlab)

《MATLAB神经网络30个案例分析》中的第13个例子，案例13 SVM神经网络中的参数优化---提升分类器性能。希望对大家有一定的帮助！(The MATLAB neural network analysis of 30 cases of example, 13 cases of 13 SVM parameters optimization of neural network classifier performance- ascension. Hope to have certain help to everybody! )

阿尔法分布的脉冲噪声，适合仿真水下环境的突发噪声(Alpha distribution impulse noise, burst noise simulation for underwater environments)

《MATLAB程序设计教程》PPT,适合初学者学习,和大家共享一下()

说明：  归一化自适应lms算法，简单易行，很适合初学者(Normalized adaptive lms algorithm, simple, very suitable for beginners)

包含多种噪声谱估计算法用于语音增强，采用的是标准谱减法，主要用于对各种噪声谱估计算法对比，详见readme.txt(Ppls spectral subtraction noise spectrum estimation, mainly used to compare the performance of different noise spectrum estimation algorithms, including Martin s minimum tracking algorithm, Minimum controlled recursive average algorithm (Cohen), variant of Minimum controlled recursive average algorithm, improved Minimum controlled recursive average algorithm (Cohen ), continuous spectral minimum tracking (Doblinger), weighted spectral average (Hirsch & Ehrilcher), connected frequency regions (Sorensen & Andersen). See readme.txt inside)

比较了几种自适应算法用于信道均衡的性能，包括LMS、NLMS、RLS等。包含仿真代码和理论的结果分析，以及自适应滤波理论的课件。(Compare the performance of several adaptive algorithm for channel equalization, including LMS, NLMS, RLS and so on. These results include simulation code and theoretical analysis, and courseware adaptive filtering theory.)

本文在确定了水声信道的数学描述后,提出了在信道自适应过程中,可以应用 子波对信号进行多分辨率分解,逐尺度地对信道进行均衡. 这样,不但减少了运算数 据量,也减少了均衡所需的权系数个数.(equalizer)

MATLAB基础教程，找了好久的，入门的抓紧学了啊(matlab_basic_book)
