SIFT_Mosaic

canny边缘检测的matlab实现，用到了基于Otsu算法的自适应阈值选取(canny edge detection)

该文档描述了如何使用sketchup制作3D模型，并上传到google的3D仓库。(This document describes how to create 3D models using sketchup and uploaded to google' s 3D warehouse.)

【实例简介】基于模板匹配的数字图片识别，使用opencv3进行图像处理

说明：  实现简单的梯度算法，这是一个函数文件。调用函数的主程序文件以及实验用的lena图都一并上传了，使用简单，快捷。注：该程序可以直接处理彩色图像。(Implementation of simple gradient algorithm, this is a function file. The main program file of calling function and Lena diagram for experiment are uploaded together. It is easy and fast to use. Note: This program can process color image directly.)

该程序通过雅可比矩阵求解Rossler系统的李雅普诺夫指数指数，并绘制了其频谱图。(The program solves the Lyapunov exponent of Rossler system by Jacobian matrix and draws its spectrum.)

这是CVPR2011论文“Single-Image Shadow Detection and Removal using Paired Regions”最新的代码，可以直接在Windows环境下直接运行，阴影检测效果很好。(This code is the latest version for the paper, Single-Image Shadow Detection and Removal using Paired Regions ,in CVPR2011.It can directly work in Windows environment and perform well. )

标准GS相位恢复算法，利用傅里叶变换与反变换进行逼近，直至收敛，误差下降算法。(Standard GS phase recovery algorithm, using Fourier transform and inverse transform approximation, until convergence, error reduction algorithm.)

将图像从笛卡尔坐标系上转换到对数极坐标上，这样做便于将笛卡尔坐标系上存在缩放和旋转关系的图像转换成对数极坐标下的具有平移关系的图像，然后就可以用相位相关检测算法进行相关检测，得到两幅图像的相关性(Convert an image Cartesian to polar coordinates on a logarithmic, this facilitates the translation relations image with the next image conversion to a logarithmic scale and rotate relationship exists between the Cartesian coordinates polar coordinates, then you can use phase correlation detection algorithm for correlation detection, the correlation between two images obtained)

对于图像运动补偿的编码，老师给的源程序，很好用(Motion compensation for image coding, the teacher to the source, easy to use)

利用马尔科夫随机场对图像进行语义分割，通过ICm求解参数，可以运行，对初学者有较好的借鉴作用(Using Markov random field to semantic segmentation of images, through ICm solution parameters, can run, for beginners have a good reference)
