利用网路摄相机来撷取影像--需配合intel的opencv的labrary

基于OpenCV的视频放大，vfw获取相机图像，进行背景积分平均后放大显示-Based on OpenCV enlarge video, vfw access to camera images, after background integral average zoom

本代码主要应用于基于CCD相机的实时动态捕捉，并进行了简单的平滑去噪，阈值化处理(This code is mainly used for real-time dynamic capture based on CCD camera, and carried out a simple smooth denoising, threshold processing)
