code for object extraction using matlab

说明：  matlab应用于神经网络：利用BP算法及Sigmoid函数，研究函数的逼近问题。(matlab applied to neural networks: the use of BP algorithm and Sigmoid function is to study the function approximation problem.)

说明：  珍藏版，可实现，新K均值聚类算法，分为如下几个步骤： 一、初始化聚类中心 1、根据具体问题，凭经验从样本集中选出C个比较合适的样本作为初始聚类中心。 2、用前C个样本作为初始聚类中心。 3、将全部样本随机地分成C类，计算每类的样本均值，将样本均值作为初始聚类中心。 二、初始聚类 1、按就近原则将样本归入各聚类中心所代表的类中。 2、取一样本，将其归入与其最近的聚类中心的那一类中，重新计算样本均值，更新聚类中心。然后取下一样本，重复操作，直至所有样本归入相应类中。 三、判断聚类是否合理 采用误差平方和准则函数判断聚类是否合理，不合理则修改分类。循环进行判断、修改直至达到算法终止条件。(NewK-means clustering algorithm ，Divided into the following several steps: A, initialize clustering center 1, according to the specific problems, from samples with experience selected C a more appropriate focus the sample as the initial clustering center. 2, with former C a sample as the initial clustering center. 3, will all samples randomly divided into C, calculate the sample mean, each the sample mean as the initial clustering center. Second, initial clustering 1, according to the sample into the nearest principle clustering center represents the class. 2, as this, take the its recent as clustering center of that category, recount the sample mean, update clustering center. And then taking off, as this, repeated operation until all samples into the corresponding class. Three, judge clustering is reasonable Adopt error squares principles function cluster analysis.after clustering whether reasonable, no reasonable criterion revisio)

复杂网络的统计参数的计算，在matlab中建立了一个m文件(The calculation of statistical parameters of complex network, established a m files in matlab)

说明：  牛顿法解微分方程的matlab code， 需要自己设定初始解(newton s method to solve PDEs)

有关如何读取视频和进行帧差计算的源码，有参考意义(codes for video reading and frames calculation)

本书既包含了数字信号处理的经典内容，也包含了部分前言内容。理论与应用相结合，特别注重应用matlab来解决理论与算法的实现问题，对于数字信号处理的学习者很实用。  (The book contains both the digital signal processing classic content, but also contains some foreword content. The combination of theory and application, with particular emphasis on applications to solve matlab realization theory and algorithms for digital signal processing learners very practical.)

说明：  遗传算法，一种启发式算法，用于演化求最优值(Genetic algorithm, a heuristic algorithm for evolutionary optimization)

说明：  广义预测控制matlab源程序，可以直接运行。只需在模型部分修改即可完成自己的目标。(Matlab source program of GPC)
