图像边缘检测

变分偏微分方程图像处理工具包，包括计算曲率，方差，L1,L2范数等29个实用算法(variational PDE image processing tool kit, including the calculation of curvature, variance, L1, L2 norm, and other practical algorithms 29)

三种图像分割法，有全局阈值otsu分割、迭代法全局阈值分割、局部阈值分割程序。(Three image segmentation method, there are global threshold otsu segmentation, iterative method global thresholding, local threshold segmentation program.)

图像高斯模糊的算法,自定义大小和模糊半径(psf of Gaussian)

图像分割，完整程序，验证可行。新手上传，望支持。(image direct)

说明：  对二维图像进行分形维数的计算，采用差分盒维数进行计算，并且进行了拟合误差的计算(The fractal dimension of two-dimensional image is calculated by using the differential box dimension, and the fitting error is calculated)

说明：  四叉树程序，图像处理，要做这个的可以看看(Quadtree procedures, image processing, that can do this look)

图像修复，使用曲率方法，热传递。边缘修复非常好，参考某博士论文写。(Image restoration, using the curvature method, heat transfer. Edge of the repair is very good, the reference of a doctoral dissertation.)

非线性CS算法,提高SAR成像的精度，弥补CSA和RDA的不足(Nonlinear Chirp Scaling Algorithm)

带通配符的字符串匹配,多重匹配,支持通配符“*”，“？”(String matching with wildcards, multiple matches, supports wildcards " *" , " ?" )

本手册主要介绍粒子滤波的基本原理和其在非线性系统的应用（主要是目标跟踪、多目标跟踪、电源寿命预测方面的应用）。同时本手册最大的优点是介绍原理和应用的同时，给出实现例子的matlab代码程序，方便读者对照公式，理解代码。因此，它是相关方面的研究者快速上手和进入研究领域的快捷工具。同时，对于有一定基础的研究者，可以在本手册提供代码的基础上，做算法进一步改进和深入研究。(This manual describes the basic principles of particle filter and its application in nonlinear systems. The biggest advantage of this manual is to introduce the principles and applications of the same time, given the matlab code example implementation program, formula for the convenience of readers, to understand the code. Therefore, it is relevant researchers to quickly get up and running enter research areas shortcut tool. , Based researchers, on the basis of this manual code to do the algorithm to further improve and in-depth study.)
