利用径向基函数的方法进行隐式表面重建，matlab代码(Radial basis function method for implicit surface reconstruction)

自己编写的一个用于人脸识别2dpca程序，很好用的，里面有中文注释(I have written one for the face recognition 2dpca procedures, well used, which has Chinese Notes)

很好用的svm工具箱，dagsvm对于图像分类效果非常好，分类精度很高，代码清洗简单。(Good use of SVM Toolbox, dagsvm for image classification effect is very good, very high classification accuracy, code cleaning easy.)

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)

三次样条曲线拟合类，可用于样条插值、拟合、预测等算法场合。(The Cubic Spline Interpolation class can be used for spline interpolation, fitting, prediction and other algorithms.)

一种基于Arnold变换的图像加密技术，并且用Matlab的GUI界面设计一个用Arnold算法进行图像加密的程序。该程序实现了Arnold图像加密算法的加、解密功能，以及一些基本的图像处理功能。(A kind of image encryption technology based on Arnold transform, and use Matlab GUI interface to design a Arnold encryption algorithm. This program implements the encryption and decryption function of Arnold image encryption algorithm and some basic image processing functions.)

非负矩阵分解法，这一种新型的子空间分解方法，增加了非负性约束，比PCA、ICA更有效(Non-negative matrix factorization method, which a new type of sub-space decomposition method, an increase of non-negative constraint, compared with PCA, ICA is more efficient)

已知Radon变换（CT原始数据）利用中心切片法则重建CT图像(Reconstruction using central slice theorem)

利用matlab实现图像的边界检测。包括sobels算子，prewitt算子，还包括图像的边界追踪(use matlab to detect the boundary of the image)
