Matlab code for demodulating QPSK signal

程序代码说明 P0401：用Prewitt算子检测图像的边缘 P0402：用不同σ值的LoG算子检测图像的边缘 P0403：用Canny算子检测图像的边缘 P0404：图像的阈值分割 P0405：用水线阈值法分割图像 P0406：对矩阵进行四叉树分解 P0407：将图像分为文字和非文字的两个类别 P0408：形态学梯度检测二值图像的边缘 P0409：形态学实例——从PCB图像中删除所有电流线，仅保留芯片对象 ( Procedure code explanation P0401: Examines the picture with the Prewitt operator the edge P0402: Examines the picture with the different sigma value LoG operator the edge P0403: Examines the picture with the Canny operator the edge P0404: Picture threshold value division P0405: Divides the picture with the water line threshold value law P0406: Carries on to the matrix four forks the tree decomposition P0407: Divides into the writing and the non- writing two categories the picture P0408: The morphology gradient examines two values pictures the edge P0409: The morphology example 鈻♀枴deletes all electricity streamline from the PCB picture, only retains the chip object )

用于对大规模文件进行操作，但对文件内容有很大的局限性，仅供参考思路(For large-scale file has many limitations, but the contents of the file are for reference only ideas)

希尔伯特变换中的经验模态分解，可对其进行局部分解，采样分解以及求取希尔伯特谱(The empirical mode decomposition, Hilbert transform its partial decomposition, sample decomposition strike Hilbert spectrum)

mean shift 用于视频序列的目标跟踪，有例子，用的MATLAB2013a，亲测，可用，改下读图地址即可(mean shift ，Target tracking for video sequences, there are examples of using MATLAB2013a, pro-test, available under change the digitizing address. )

n多文章全部是IEEE上的关于多速率信号处理的内容，包括均匀和非均匀调制滤波器组的应用。其中cmfb.m为matlab文件，是A Kaiser Window Approach For The Design Of Prototype Filters Of Cosine Modulated Filterbanks的源代码，是老外给的M文件，很有参考价值。(n number of articles on all of the IEEE Signal Processing on the multi-rate content, including uniform and non-uniform application of modulated filter banks. Matlab file for cmfb.m which is A Kaiser Window Approach For The Design Of Prototype Filters Of Cosine Modulated Filterbanks the source code, is a foreigner to the M-file, a good reference.)

LASSO程序,非常经典的LASSO程序，适合数据挖掘、特征选择(LASSO Matlab code，Data mining and machine learning)

这是一份SAR图像变化检测的matlab源代码，通过处理两幅SAR图像的差异图，进行数学形态学处理和聚类分析等方法实现图像的变化检测。(This is a SAR image change detection matlab source code, through the differences the two SAR images processing plan and make mathematical morphology processing and cluster analysis to achieve change detection image.)
