用Matlab实现的多种基于阈值的图像分割方法，含有大津法，最大熵，聚类等方法(Using Matlab to achieve a variety of threshold-based image segmentation method, which contains Otsu method, maximum entropy, clustering and other methods)

这是对广义高斯分布中两个参数alpha,beta的估计方法，对自然图像的大量统计特征就符合这一分布。(function [f, g] = dggbeta(beta, absx) DGGBETA Derivative of generalized Gaussian pdf with respective to beta [F, G] = DGGBETA(BETA, ABSX) Return partial derivative and second order partial derivative This is an utility function for GGMLE ABSX is the distance of the data from the mean Function is undefined for negative beta if beta <= 0 f = NaN g = NaN )

这是mimo ofdm系统的仿真程序，代循环前缀，加性高斯噪声，双发双收的系统，(Channel estimation for a MIMO-OFDM system estimation technique subcarriers)
