这是用VC6.0编写的绘制三次Bezier曲线的程序，使用MFC框架文档视图结构。程序除实现三次Bezier曲线的绘制，还实现了点，直线，圆的绘制，可做为学习计算机图形算法的参考。与其它Bezier曲线绘制程序的不同是，本程序实现了Bezier曲线上型值点的计算显示。程序中编写了Bezier曲线类来完成Bezier曲线的绘制，并能对绘制的曲线数据进行保存与打开。对学习文件操作也有一定帮助。这是我第一次上传源码，有什么不妥之处还请管理员指点。谢谢！-VC6.0 prepared by the cubic Bezier curve drawing procedures, use MFC framework document View structure. In addition to procedures to achieve cubic Bezier curve drawing, but also realized the point, line, round mapping, can be used as learning computer graphics algorithm reference. And other Bezier curves of different procedures, The program of Bezier curve-point value calculations show. Procedures prepared Bezier curves like to complete the Bezier curve drawing, and is able to draw the curve data preservation and open. Operation right to study the documents will also help. This is the first time I uploaded the source code, what is wrong with this manager also requested guidance. Thank you!

切换屏幕在原始尺寸与全屏中切换，而且向你演示即使全屏文字也不会按比例放大，还有一个退出动画的按钮；不过你可能要DOWN回去之后才能看到它的效果-Switch the screen size and full-screen in the original switch, but also to the presentation you will not even full-screen text in proportion to enlarge, there is a quit button animation but you may have to go back DOWN to see it after the effects of

应用背景 SIFT特征匹配算法, 在没有先验知识条件下, 对旋转、尺度缩放、光照、视角变化等图像变化因素保持一定鲁棒性, 且对低重叠区域(30%左右的相似重叠区域)、部分遮挡(只出现在其中一张图上的物体)和噪声等因素也保持较好的可匹配性。可用于多尺度下的特征匹配，以及鲁棒性的图像拼接。 关键技术 1.高斯尺度空间极值检测 2.特征点位置的确定 3.特征点方向的分配 4.生成SIFT特征向量 5.图像拼接 6.图像融合 提取图像的sift特征，构造特征描述子，基于sift特征构造BBF-tree，根据描述子之间的欧式距离进行初步的匹配，然后进过鲁棒的Ransac估计出最佳运动模型H，然后用距离加权的方法在重叠区进行融合。

本人收集的人脸识别最新资料，从08年到09年，包含各种人脸识别的优秀算法，PCA,HMM,2DPCA,KDDA,一共20个文件，需要安装CAJ阅读器阅读，是不可多的学习和研究的参考资料（不是源码，算法详细）-I gather the latest information for face recognition, from 2008 to 2009, contains an excellent variety of face recognition algorithms, PCA, HMM, 2DPCA, KDDA, a total of 20 files, need to install CAJ readers to read, is not more than study and research references (not the source, the algorithm in detail)
