| 摘 要： | 研究了一种实时人脸跟踪方法。针对运动过程中人脸大小、形状都会发生变化的特点,采用直方图非参数密度估计作为人脸模板及人脸候选区域的模式特征,并通过Bhattacharyya系数度量其相似度。在人脸跟踪过程中以均值偏移为核心算法,通过均值偏移矢量的迭代,在局部得到最匹配人脸。最后给出实验结果,验证了跟踪方法具有很好的实时性,并对人脸姿态变化、旋转及被短时遮挡具有较好的鲁棒性。

| Abstract: | A method for real-time face tracking is presented.Based on the fact that the size and pose of a face will vary when it moves,the paper uses the histogram to describe the features of the face model and its candidates,and measures the similarity through the Bhattacharyya coefficient.The core searching method is the mean shift algorithm.By the mean shift vector iteration,we find the most matching face in local place.The experiments finally show that the tracking satisfactorily meets the real-time requirement and is robust to the face scale variation,rotation and fast occlusion. |
