The purpose of this demo is to perform axis-aligned bounding box collision detection. If collison has occured then the camera will stop moving in that direction, else it will continue. Controls: Arrow keys - Moves the camera.-

人脸检测C源程序，主要是最小外接矩形算法和椒盐去噪，中值滤波的实现程序。-Face Detection C source, minimum bounding rectangle algorithm and salt and pepper denoising, the realization of the program of the median filter.

c 实现了以点阵表示的多边形的最小外接矩形，并求出其的面积。-c to achieve a in order to dot-matrix expressed of polygons of the minimum bounding rectangle, and calculated its of the area.
