| 摘 要： | 简述了近年来主要的人脸跟踪方法,提出一种基于帧间差分与静态特征相结合的人脸跟踪算法。算法利用视频图像的运动信息做帧间差分确定人脸搜索的矩形区域,利用肤色模型提取肤色区域,通过积分投影确定人脸的椭圆范围,并对矩形范围内图像做边缘提取、膨胀等处理,通过水平积分投影获得人脸特征曲线,并通过特征曲线验证椭圆范围内是否存在人脸,实现人脸自动跟踪。

| Abstract: | The main methods of face tracking were introduced,and a new method based on both inter-frame differential and static character was put forward.The method makes inter-frame different using the movement information of video-image and obtains the face's approximately rectangle district and pick-up the complexion area with the complexion model,and distilsl the face-edge in the rectangle area.Then,the image was expanded and the level-projection was made.The character curve was used to validate the existing face in the complexion area.Consequently,automatically face tracking is realized. |
