Gradients

说明：  给出一些离散的点，根据最小二乘法求出拟合的直线。(If there are some discrete points, you can get a line based on least square method.)

对图像进行欠采样，然后利用OMP 进行重构，其中用到了小波矩阵进行稀疏(The image is undersampled and then reconstructed by OMP, in which the wavelet matrix is used for sparsity.)

这个程序是用来绘制光子晶体光纤的色散曲线。(This program is used to draw the dispersion curves of the photonic crystal fiber.)

利用matlab软件仿真斜条纹和竖条纹的干涉图样(Software simulation using matlab interference pattern diagonal stripes)

在各种图形中，通过提取点的凹凸部分来鉴别曲线的特征，本节代码利用曲率关系分别提取凹点的个数，判断曲线的弯曲(In a variety of graphics, through the extraction point to identify curves convex-concave part of the characteristics of the code used in this section were extracted from concave curvature of the relationship between the number of points to determine the bending curve)

这是一个基于二维的2D组合交互程序，可以随意加到自己相关程序中(This is a combination of 2D interactive program based on a two-dimensional, can be freely added to their program)

说明：  采用水平集（level set）方法和mumford-shah图像分割模型的图像分割matlab源代码。(horizontal Collection (level set) methods and Mumford- shah Segmentation Model Image segmentation Matlab source code.)

visual c++实现voronoi图生成函数的实现 voronoi图生成与构造(voronoi implements with visul c++)

对学习独立成分分析和人脸识别的会很有用，希望对大家有所帮助！(Learning independent component analysis and face recognition will be very useful, and they hope to be helpful to everyone!)
