image segmentation algo implementation using matlab

基于MATLAB的16QAM仿真设计，里面包括若干个M文件，使用者只要在MATLAB环境下运行，就能看到仿真结果。(MATLAB simulation of 16QAM based on the design, which includes a number of M documents, users simply run under MATLAB environment, you can see the simulation results.)

This is code for Haralick feature extraction for image in matlab. The basis for these features is the gray-level co-occurrence matrix. This matrix is square with dimension Ng, where Ng is the number of gray levels in the image. Element [i,j] of the matrix is generated by counting the number of times a pixel with value i is adjacent to a pixel with value j and then dividing the entire matrix by the total number of such comparisons made.

实现扩频里随机信号和伪码序列的产生，以及扩频信号的产生，用本地载波实现bpskt调制，在接收端用差分相干积分完成伪码捕获的相应MATLAB程序(Spread spectrum signal generated in the realization and pseudo random code sequence, and generate a spread spectrum signal modulation to achieve bpskt local carrier, at the receiving end with the completion of the pseudo-differential coherent integration of the corresponding MATLAB code acquisition program)

说明：  该算法采用如下共聚类结构进行多重聚类： 1.优化地将数据集划分为多个视图。在每个视图中，对象和特征都是群集的。 2.同时分析了三类特征：高斯特征、泊松特征和范畴特征。 3.自动推断视图和簇的数量。(This algorithm carries out multiple-clustering with co-clustering structures as follows: 1.Optimally divides datasets into several views. In each view, both objects and features are clustered. 2.Simultaneously analyzes three types of features: Gaussian, Poisson and categorical features. 3.Automatically infers the number of views and clusters.)

数字信号处理综合设计 利用windows下的录音机录制一段自己的话音，时间控制在1秒左右；并对语音信号进行采样，理解采样频率、采样位数等概念。(Digital signal processing integrated design Using Windows, making a video recorder under his voice, time control in 1 seconds And the voice signal sampling frequency sampling, understand concepts, sampling digits. )

MATLAB给图像添加高斯、椒盐、加性及乘性噪声[噪声生成]源代码Gaussian-Pepper-Noise-Generator(MATLAB——Gaussian-Pepper-Noise-Generator)

该函数用于二维曲面拟合，能拟合出f=（x，y）的函数图形。(Gridfit is a surface modeling tool, fitting a surface of the form z(x,y) to scattered (or regular) data. As it is not an interpolant, it allows the existence of replicates in your data with no problems.)

雷达后向投影算法。利用雷达接收到的数据的时延来成像。具有很大的应用价值。(After the radar to the projection algorithm. Using the delay of the received radar data to imaging. Has great value.)

极化SAR定标处理的matlab程序，采用最新的Ainsworth算法(Polarization SAR processing matlab calibration procedure, using the latest algorithms Ainsworth)
