此文件是用matlab解决商人渡河问题的。。。。。。。。(Solve the problem of merchants across the river)

粒子群算法的寻优算法，非线性函数极值寻优，MATLAB的经典算法(Particle swarm optimization algorithm, nonlinear function optimization extreme, MATLAB classical algorithm)

堆栈自编码，通过两个稀疏自编码的堆叠和softmax分类模型，实现手写体的分类。(Stack self-encoding, since encoding by two sparse stack and softmax classification model to classify handwriting.)

这个是以fuzzy特征为例采用HMM方法进行分类的程序，里面用到的一些子函数都可以在HMM Toolbox里面找到(This is a classification code using HMM and taking fuzzy as example.the subfunctions in it can be find in the HMM toolbox.)

参数a,b,n对r=acos(nt+b)的影响，观察菜单和图形的变化，体会相应的程序控制逻辑(The parameters a, b, n r = acos (nt+b) the impact of observed changes in the menu and graphics, the experience of the corresponding program control logic)

说明：  本文以室内、外不同空间的人数统计为背景，研究基于图像的人员计数技术，对某时段内进出摄像机视野中指定区域的人数，或指定区域内在景人数进行统计。主要研究内容有以下几点： （1）人员计数方案论证：本文分析对比了不同人员计数算法，研究分析了基于像素、 基于Hough变换的人员计数算法的优缺点。 （2）基于像素统计的人员计数系统实现：①分别采用近似中值背景模型和高斯混合背景模型提取前景图像；②采用基于HSV颜色空间变换的方法对前景中的阴影进行抑制；③用前景像素数除以人数得到一个人的像素平均值，在已知图像中前景像素数的情况下，可对人数进行估计。 （3）基于Hough变换的人员计数系统实现：①根据人头顶部轮廓近圆的特征,采用Sobel算子提取图像边缘,得到目标轮廓；②设置人员检测计数区，利用Hough变换进行圆检测；③对目标进行跟踪，并且进行有效性判断，记录有效目标；④判断行人是否跨线及跨线方向，实现过往行人的双向人数统计，并对人头进行标记。 (In this paper, indoor outside the different number of spatial statistical background image based on studies of people counting technology, the number of designated areas within some period of time and out of the camera view, the number of designated areas or inner view statistics. The main contents are as follows:       (1) people counting demonstration program: In this paper compares different people counting algorithm analysis based on pixel count algorithm based on the advantages and disadvantages personnel Hough Transform.       (2) based on pixel count of people counting system achieve: ① were used to approximate the value of the background model and a Gaussian mixture background model extraction of the foreground image ② the method of the HSV color space conversion based on the foreground shadow suppressed ③ foreground pixels divided by the average number of pixels to obtain a person s image at a known number of pixels in the foreground of the case, th)
