Required by the intelligentizing of video monitor system,this paper proposes a face detection design based on embedded video monitor.With the help of the transaction of Servfox streaming media on ARM-Linux operation platform,the collection and transmission of USB camera are realized.This paper adopts the inter-frame difference to renew the background and that can track the moving target and at the same time to lessen the influence of the moving target on the background model.It narrows the scope of detection of the human face.It locates the human face by AdaBoost human face detection in the target moving area.The system performs well on human face detection and the correctness reaches 95.2%.The detection time is 22~27 ms/frame.It satisfies the real-time requirement of the video monitor.
