说明：  光谱数据降维处理，结合了主成分分析和LDA方法，可直接运行(Spectral data dimensionality reduction processing, combined with principal component analysis and LDA method, can be directly operated)

变分法基础pdf 基本理论知识，希望对大家打下理论基础，(this is basic theory for math.)

说明：  基于ADMM的TV正则化最小化稀疏重建算法(TV Minimization Sparse Reconstruction Algorithms Based on ADMM)

基于均值漂移的图像平滑MATLAB源戴码。(Based on mean-shift image smoothing Dai MATLAB source code.)

能够实现图像分割，对图像分类起到一定的分割效果(Image segmentation can be realized)

用Graph cuts 来解决磁共振图像的 phase unwrapping。(Graph cuts used to solve the magnetic resonance images of the phase unwrapping.)

我自己做的一个bmp文件进行24位真彩转256灰度和二进制的程序，并能用sobel算法，识别物体的边界。 (I myself make a bmp file for 24-bit true color to 256 gray-scale and binary procedures and sobel algorithm can be used to identify object boundaries.)

代码主要用来模拟林芝机场附近一天内4个不同时间GDOP变化情况(Code is mainly used to simulate the Nyingchi Airport near four different times within a day GDOP changes)

harris角点检测，并且实现两幅图像特征点的匹配，最终完成图像的拼接(harris corner detection, and realize two image feature point matching, the final completion of image stitching)

non-local means denoising 自己实现的非局部均值图像去噪的原始算法，对理解算法原理有一定帮助(Non-local means denoising： an implementation of the non-local means denoising of the original algorithm, some help understanding algorithm)
