基于C#上的EMGUCV编写的SIFT算法的代码，自己修改匹配库的文件图片即可，支持显示SIFT的关键点(EMGUCV C# based on SIFT algorithm written in code, make changes to the document image to match the library, support the display of the key points SIFT)

图象分割程序：先用梯度函数进行边缘检测,然后二值化后分割图象(Image segmentation process: first the gradient edge detection function, and then after binarization image segmentation)

基于直接最小二乘法的椭圆拟合程序，比较实用，适用于图像处理，椭圆拟合方面研究的初学者(Direct least square method based on ellipse fitting procedure more practical for image processing, aspects of ellipse fitting for beginners)

ENVI二次开发去云处理补丁，可用于去除薄云影响(ENVI secondary development to cloud processing patch, can be used to remove the cloud-affected)

实现了添加水印及攻击水印的一些方法。攻击水印方法包括抖动攻击、滤波攻击、旋转攻击等(Add watermark and implementation of a number of methods to attack the watermark. Watermarking attack methods include jitter attacks, filtering attacks, spin attack)

这个是最成熟的人脸检测算法viola-jones的matlab版本实现，适合搞研究的同学们(a matlab implementation of the viola-jones face dection!)

边缘检测法和阈值分割法，是图像分割技术应用中两项重要的方法。本文介绍了图像边缘检测和阈值分割的一般原理、典型算法以及研究现状。本文针对边缘检测算子和几种阈值分割技术进行了详细讨论。针对火柴根数统计和钢筋根数统计两个实验，在详细分析检测原理的基础上，编写了相应的实验并给出了实验结果。(Edge detection and thresholding method, image segmentation is an important technology in two ways. This article describes the general principles of image edge detection and thresholding, the typical algorithms and research status. In this paper, several edge detection operator and thresholding techniques are discussed in detail. Statistics for the number of matches and reinforced the number two experimental statistics, based on a detailed analysis of the detection principle, write the corresponding experimental and experimental results are given.)

sift算法的完整matlab程序,本人测试过，很好，稍加修改即可！(complete sift algorithm matlab program, I tested, well, a few minor changes!)

说明：  用VB做的图像二值化的代码,希望能对大家有帮助(vb image test)
