| 摘 要： | 为了提高动态图像序列中人脸轮廓跟踪时梯度矢量流(GVF) Snake算法的实时性,同时解决人脸跟踪中的遮挡问题,提出了GVF Snake和单变量一阶灰色模型GM(1,1)相结合的人脸轮廓提取方法.该方法首先利用人脸运动信息和肤色模型粗略地检测出运动人脸轮廓,然后采用GVF Snake算法将人脸轮廓精确地提取出来,从而有...

| Abstract: | In order to improve the real-time performance of the Gradient Vector Flow Snake(GVF Snake) algorithm for face contour tracking in a dynamic image sequence and to overcome the occlusion problem in face tracking,a novel image extraction method combining the GVF Snake algorithm and the single variable first-order grey model GM(1,1) is proposed to extract the face contour.In this method,the moving face contour is roughly detected out firstly by using human motion information and the skin-color model,and then th... |
