imnoise的M文件，对数字图像的加噪声非常有用处！(imnoise M-files, plus noise on digital images is very useful!)

高阶频谱分析工具箱，老外写的代码，可以用来做实验(High-order spectral analysis toolbox, a foreigner writing code that can be used to experiment)

全极化干涉雷达图像分类算法的实现代码full_wishartdec(Polarimetric InSAR image classification algorithm implementation code full_wishartdec)

利用霍夫曼编码对图像进行编码及解码，计算霍夫曼编码效率(huffman encode and decode)

利用传统的SVM-HOG算法，进行行人检测(HOG-SVM algorithm for pedestrian detection)

将黑白图像转换成灰度级—邻域平均灰度级二维直方图(Black and white images will be converted into gray-scale- the average gray-scale neighborhood of two-dimensional histogram)

非下采样轮廓波变换与二维主分量分析的循环模式计算(nonsubsambled contourlet transform and two dimensional principle component analysis cycle module calculation)

说明：  使用unet对图像进行分割的源码，里面有训练集，可以根据自己的需要更换训练数据。(Use the source code of the image segmentation using UNET, which has a training set, you can change the training data according to your own needs.)

说明：  自己写的fft的应用实例，包括对一维振动信号分析，对二维图像频谱分析。(The application examples of FFT written by myself include one-dimensional vibration signal analysis and two-dimensional image spectrum analysis.)

对张正友标定得程序重新详细标注了中文注释，方便初学者尽快入门，在最短的时间内了解程序流程，提高学习效率！(Zhang Zhengyou matlab calibration procedures, in order to facilitate a beginner, a code re-done every detail marked Chinese comments, so that we can understand the flow of the program as soon as possible!)
