高光谱数据进行KNN分类，可以从原始数据如（indianpine）中选取部分样本(Hyperspectral data can be classified by KNN, and some samples can be selected from raw data such as (indianpine).)

说明：  机载正侧视SAR雷达仿真和成像，使用matlab编写，直接运行可用(Simulation and imaging of airborne forward-looking SAR radar)

一种基于小波的图像分块处理并且水印嵌入和提取，适合初学者学习使用(Based on wavelet image processing block and the watermark embedding and extraction, suitable for beginners learning to use)

pca特征提取子程序，毕设用的，算法优化非常好，几乎没有循环，相当节省时间，堪称经典，运行绝对正确！！(pca feature extraction subroutine, used to complete set up, very good algorithm, almost no circulation, saving considerable time, classic, run absolutely right! !)

图片排序效果。根据你拖动的位置来进行排序(The picture sort of effect. Depending on where you drag to sort)

说明：  再来一个绘图程序，花了我一个上午时间才搞定。(then a drawing program, I spent a morning time to get.)

说明：  多尺度多方向性的剪切波Shearlet变换优于小波变换，里面包含很多例子，可以直接运行，可以用于图像去噪，分割，增强等，是一个优于小波的图像稀疏表示工具(Shearlet transform of multi-scale and multi-directional shear wave is better than wavelet transform. It contains many examples and can run directly. It can be used for image denoising, segmentation and enhancement. It is an image sparse representation tool better than wavelet transform.)

点云特征提取 详细 实用 经典的讲述过程及方法(Point Cloud Feature Extraction practical details about the processes and methods of classic)

把图像导入后，可以实现对图像的huffman编码(Import the images, you can realize the image of the huffman encoding)

RGB颜色转换源码程序，根据RDB颜色组成结构，使用位运算实现RGB颜色转换。(RGB color conversion source program, according to RDB color composition structure, using bit operations to achieve the RGB color conversion.)
