摘要
人脸自动定位技术在智能视频通信、视频监控以及娱乐等领域有着广泛的应用。通过将基于肤色的人脸检测和基于人工神经网络的控制策略相结合,提出一种新的人脸自动定位算法。该算法简单有效,克服传统跟踪算法中需要利用帧间相关信息和需要标定摄像机的缺点,只需通过人脸检测程序给出人脸特征点在计算机图像中的坐标,就可直接得出摄像机水平调整量和垂直调整量,根据调整量控制摄像机运动即可将人脸自动定位在图像中心。最后利用面向对象的方法实现了系统,并且取得了满意的效果。
Face auto - location has a wide range of usage, such as intelligent video communication, video surveillance and entertainment. A new approach to face auto - location based on traditional face detection and new artificial neural network control strategy is proposed. The algorithm is simple and effective. Neither requiring the information of correlative frames nor camera calibration, the algorithm can locate the faces＇ feature point in the image center quickly using the face feature points and coordinates. Implemented by object- oriented method,the system works fine and has practical value.
