用vibe算法提取动态背景的前景信息，背景为白色(Vibe algorithm is used to extract foreground information of the dynamic background, the background is white)

提取人脸表情库中的图像数据,可提取任一种表情、任一个人或任一复本(extract the image data of facial expression database:JAFFE database。it is able to extract any expression, subject and copy of JAFFE database)

说明：  相机是将三维世界坐标系中的坐标点映射到二维图像平面的过程能够用一个几何过程描述，最简单模型称为针孔模型。 因为相机镜头透镜的存在，使得光线投影到成像平面过程中产生了畸变。(Camera is the process of mapping coordinate points in three-dimensional world coordinate system to two-dimensional image plane, which can be described by a geometric process. The simplest model is called pinhole model. Because of the existence of camera lens, the light rays are distorted when they are projected onto the image plane.)

Matlab版改进的sobel算子边缘检测算法，有效减少边缘断点(Matlab version improved sobel operator edge detection algorithm is effective in reducing edge break)

基于NCC与SSDA的快速特征点匹配融合算法（图像匹配）(NCC and the SSDA-based feature points matching the rapid integration algorithm (matching))

一种快速的多边形和矩形检测算法，可以广泛的应用于各种目标识别领域(A fast polygon and rectangle detection algorithm can be widely used in various areas of target identification)

meanshift图像分割 1.mean shift 的迭代过程只做了一次（为了简单） 2.对图像中的某一点进行平移时，只考虑了距离它小于2*hr的点，而不是图像中所有的 点。 3.实验过程中只用到了gauss核，虽然提供了method的选择，但在进行值域加权时只用 到gauss核，如果需要请自己改正。(meanshift segmentation)

SURF算法为SIFT算法的改进，运算速度得到了很大的提高。本资料为基于MATLAB的SURF算法实现，对图像匹配的研究方向会有一定帮助。(SURF algorithm SIFT algorithm, computing speed has been greatly improved. MATLAB based on the information of the SURF algorithm for image matching the direction of the research will certainly help.)

详细说明：几个关于图像灰度变换的程序。包括图像反色，图像的对数灰度变换，指数灰度变换，线性灰度变换，灰度切割，图像平均降噪。 (Several of the image gray-scale transformation process. Including anti-color image, the image of the number of gray level transformation, index gray-scale transformation, linear gray level transformation, gray cut, the average image noise.)

多边形的合并算法，该算法能够实现任意两个多边形（包括凹多边形）的合并.( The polygon merge algorithm, this algorithm can realize wilfully two polygons (including concave polygon) merge )
