ARDUINO PCF8564 library. Source code

基于MATLAB的图像区域分割和合并算法，包含3个m程序。(Image segmentation method based on regional division of merger)

CDMA编码的代码,跳频扩频的代码以及直接序列扩频的代码，以及GOLD码产生(CDMA coding ,FH Spread spectrum and DS Spread spectrum )

该程序可以构造一个不同行重列重下的QC-LDPC码，并做性能仿真(constructs qc-lpdc codes given size of sub-mnatrix(m), girth(g1), row (k) and column(j) weights)

说明：  GCC时延估计，二次互相关进行估计时延，精确定位(GCC delay estimation, the second cross-correlation to estimate the delay, precise positioning)

用MATLAB写的宽度优先搜索函数，支持障碍设置和四叉树/八叉树的选择，在路径搜索方面有用。(First search function using MATLAB written in width, support the obstacles set up and quadtree/octree useful in terms of route search.)

广义互相关函数来确定两个信号的时延差，时延定位相关程序(Generalized cross-correlation function to determine the time delay difference between the two signals, the delay positioning procedures)

Gaussian Mixture Model test

擅 蔓：以人脸的表情识别为实验背景， 分析了在对人脸表情的识别过程中，单个独立分薰对识别率的影响，由此进一步总结了在表情识 别中如何更有效地选取独立子空间，以实现在不影响识别率的前提下，减少用于构成独立子空问所需的独立分量的个数。 独立成分分析；表情识别；独立子空间 (Good man: Face to face identification for the experimental background, the analysis of facial expressions in the identification process, a single smoked separate the impact of the recognition rate, thus further summarized in the expression recognition of how to more effectively select the independent sub-space in order to achieve the recognition rate does not affect the premise, for constituting a separate sub-reducing space required for the number of independent component. Independent component analysis expression recognition independent subspace)

说明：  用MATLAB实现的灰色理论代码，采用word的格式。欢迎下载。(Implemented using MATLAB code for gray theory, using word format. Welcome to download.)
