图像的正交变换，傅立叶变换，离散余弦变换，沃尔什变换，哈达玛变换...

从前用matlab编的人脸识别的特征提取以及识别程序，希望有用-The previous series of face recognition using matlab feature extraction and identification procedures, seek to help

椭球体的碰撞检测。在以人形为主的场景内椭球体的碰撞精度比球体、AABB、OBB都要高，同时速度也很快-Ellipsoid collision detection. Human-oriented in the scene of the collision within the ellipsoid accuracy than the sphere, AABB, OBB higher speed quickly at the same time

SIFT（Scale-invariant feature transform）是一种检测局部特征的算法，该算法通过求一幅图中的特征点（interest points,or corner points）及其有关scale 和 orientation 的描述子得到特征并进行图像特征点匹配，获得了良好效果，详细解析如下： 算法描述 SIFT特征不只具有尺度不变性，即使改变旋转角度，图像亮度或拍摄视角，仍然能够得到好的检测效果。整个算法分为以下几个部分：

指纹识别原理和算法-the principle and arithmetic of fingerprint identify

BD牌识别定位程序+挺不错的+实现功能简单-asdgasg

三维计算机图形学点透视投影变换与双3次Bezier曲面绘制算法，很有用的哦。在VC++6.0下编译通过。-point perspective projection transform and double three times Bezier surface rendering algorithm, Oh, very useful. In VC 6.0 compiler passed.

这段程序，实现了上述的膨胀运算，针对的都是黑色点。-this process, achieve the above expansion computing has been aimed at Black Point.

自己用C语言编写的中点画圆算法，根据用户输入的圆心坐标和半径画出相应的圆形。-own use C language prepared by the midpoint drawcircle algorithm, According to user input center coordinates and radius of the circle corresponding paint.

对任意多边形进行切割，求其相交部分,相交部分用红色线段标出。-draw two polygon and then they can cut each other.The color of intersected parts are red.

随意在平面上绘图并有位图顺着轨迹移动-at random plane graphics and bitmap along the trajectory mobile
