PCA-SIFT

sift Algorithm made by David Lowe sift demo

这是一个阈值分割算法，主要用来对图像进行二值化，提取感兴趣区域~~(This is a threshold segmentation algorithm, mainly used for binary images, extract region of interest ~ ~ )

说明：  基于matlab的指纹识别源码 包括预处理、特征点提取和特征点匹配(Fingerprint recognition source code based on MATLAB includes preprocessing, feature extraction and feature matching)

一个非常好的粗糙集的代码-希望对大家学习提供参考(Rough set a very good code- I hope to provide reference for all of us to learn)

能实现最小包围盒法方格划分，并利用中值进行点云精简(The minimum bounding box method can be implemented and the median value can be used to simplify the point cloud.)

用加密代码将文字隐藏在图片中，用解密代码将文字提取。c++(The text is hidden in the picture with encrypted code, and the text is extracted with decryption code.)

RGB和LAB色彩转换源码程序，根据颜色组成原理通过计算实现RGB和LAB色彩转换。(RGB and LAB color conversion source program , according to the colors of the RGB and LAB color principle to achieve conversion by calculation.)

三维图像重建,采用多种滤波方法，实现三维图像重建，该算法效率比较高。目前已经应用到实际工程。(3-dim picture recreat,use filter method and project method to realise the recreating of 3 dim picture.it is a very effective method ,applied in the project.so I share it with you . )

应用matlab或VC语言编制的图像处理源程序，适合课程设计。(Application matlab or VC image processing source code compiled language for curriculum design.)

说明：  一种彩色图像的边缘检测算法，检测效果非常好，它是对Canny算法的改进，定位好，相应标准高，检测率高，误检率低(a kind of edge detection algorithm.The algoritlun employs amultpassprocessing approach that re}novesnoisefrom theRGB componentswith apre-filter, with the color edge detector then based on an extended gray scale edge gradient tern plate detector.)
