| 摘 要： | 针对单视觉通道唇读系统的唇部特征提取问题,提出了基于唇部灰度能量图的特征提取方法.该方法将表示字或词的图像序列投影到二维灰度能量图上,不但统一了输入数据的维数,而且较好地保留了序列图像的运动信息.针对模板匹配方法对模板的依赖问题,文中将单训练样本唇部灰度能量模板图推广至多训练样本.文中还就唇部定位提出中心定位法.实验结...

| Abstract: | In this paper,by taking the visual-only lipreading system as the research objective,a method to extract the visual lip feature based on the lip gray energy image(LGEI) is proposed.In this method,the image sequences of a word are projected to the 2D lip gray energy image to unify the dimension of input data and maintain most motion information of image sequences.In order to eliminate the dependence of the template matching method on the template,the LGEI of the single-training sample is extended to the multi... |
