摘要
文章提出了一种在实时视频安保系统图像中快速检测人脸和定位人脸的方案,并利用VC++6.0设计了一套基于PC机的软件将其实现。对摄像机实时采集的图像,首先利用差分检测的方法,剔除大部分背景区域,然后利用肤色检测准确定位人脸。实验证明该方法快速、有效适用于实际的视频安保系统。
A face detection method that can be applied to real-time video-based security system is proposed. and then is realized using VC++6.0.Firstly two image captured by camera dynamically (one is the background) were subtracted to select the region that maybe include a man. And then use skin color to detect the face from the region.
