Face to face recognition algorithm to identify the snake algorithm

SIFT算法由D.G.Lowe 1999年提出，2004年完善总结。后来Y.Ke将其描述子部分用PCA代替直方图的方式，对其进行改进。 2 SIFT 主要思想 SIFT算法是一种提取局部特征的算法，在尺度空间寻找极值点，提取位置，尺度，旋转不变量。 -a method for extracting distinctive invariant features from images that can be used to perform reliable matching between different views of an object or scene. The features are invariant to image scale and rotation, and are shown to provide robust matching across a a substantial range of affine distortion, change in 3D viewpoint, addition of noise, and change in illumination. The features are highly distinctive, in the sense that a single feature can be correctly matched with high probability against a large database of features from many images.

本代码可以对任一BMP文件进行读写操作，方便后期的处理-This code can be any one of BMP files to read and write operations, to facilitate the latter deal with

（1）对512*512的256色位图进行锐化效果处理、浮雕效果处理。 （2）对图像进行柔化效果的处理。 （3）对图像进行加强柔化及锐化效果的处理。 -(1) 512* 512 256-color bitmap for sharpening effect of treatment, relief effects processing. (2) softens the effect of image processing. (3) to soften and sharpen images to enhance the treatment effects.

VB将图像拖动到任意打开的窗口上，比较有意思，你只需拖动窗体中的小箭头到任意目标窗体，松开鼠标后图像就跑到目标窗体上了，不过程序还需要完善，有时候图片会被遮挡住，只实现了基本的思路，不是太常用，就当是一个学习资料吧。-VB drag the image to any open window, the more interesting, you just drag the form of small arrows to any objective form, release the mouse after the picture ran on the target form, but the program also need to perfect, and sometimes images will be blocked to live, only to achieve the basic ideas, not too common, it is a learning information when the bar.

各种图形图像处理的源代码，用VC++实现,如包括图象的边缘检测与图象分析源代码、图象增强源代码、图象的几何变换、图象灰度变换源代码等。-various patterns of source code, with VC. If the images including edge detection and image analysis of the source code, source code image enhancement, image geometry transformation, Gray Image Transform source code, and so on.

基于多特征描述和DPF区域匹配的图像检索-Based on multi-feature description and matching DPF Regional Image Retrieval

在VC6.0中的一些基本操作,常常用来进行简单的学习和常规的练习 -in VC6.0 of some of the basic operations, often used for the study and simple conventional exercise

c++图行图像处理，图像的直方图均衡化。-c++ map line image processing, image histogram equalization.

高斯背景建模的C++程序，里面有用到OPENCV。-Gaussian background modeling C++ Procedures, which useful to OPENCV.

本代码实现的功能：24位位图（BMP）的灰度化。具体实现过程：打开图像文件,找到数据区(每3个字节代表一个象素的R,G,B值),循环扫描,根据RGB的权重,计算出灰度值. 如果要得到256色灰度图,则要新建一个调色板,修改信息头和文件头.-Realize the function of the code: 24-bit bitmap (BMP) of the gray. Concrete realization of the process: Open the image file, locate the data area (3 bytes per pixel on behalf of a R, G, B values), cyclic scan, according to the weight of RGB, gray value is calculated. If you want to get 256 colors grayscale, would create a new palette, modify the header and file header information.
