| 摘 要： | 鉴于实时视频图像采集处理技术在安全监控、视频会议、网络聊天等领域正得到越来越广泛的运用,文中介绍如何利用VideoforWindows库函数来构建视频图像的采集框架;由于回调函数是各种型号视频采集卡处理视频图像的通用接口,分析了如何自定义回调函数来实时处理采集的视频数据,并利用梯度差分法来实时检测视频图像的活动轮廓,该方法可运用于视频目标监控、人脸检测等视频图像处理项目。

| Abstract: | Since the growing application of realtime video acquisition and process technology in the fields of security moniter,video conference and network chatting,this paper introduces how to develop the framework of video image acquistion project based on video for windows library;and because call-back function being the common interface of video card on capturing and processing video data,this paper analyzes how to process the acquired video data in real time with self-defined call-back function,and explains the adoption of grads differential method to acquire the active contour of video image in real time, which could be applied in the video image processing project,such as video object moniter, face detection. |

| Keywords: | capture window self-defined call back function grads differential image |
