| 摘 要： | 唇部检测是唇读识别的基本步骤,在研究人类视觉和唇色聚类的基础上,分析了唇色和肤色的聚类性,提出了基于惩罚感知器学习算法对彩色人脸图像的唇部进行定位的新方法.实验表明,采用感知器学习算法只需对所有输入图像进行一次训练样本的采集,就可以得到了正确的权阈值,准确对所有不同人脸的唇部图片进行定位,相比于Fisher变换每次都需对输入图像进行样本采集,感知器学习算法唇部定位更准确,轮廓更清晰,且更具有通用性,有利于唇部口型的识别.

| Abstract: | Lip detection is the basic step of lip recognition.Based on the research of human vision and lip color clustering features,The paper here analyzes the clustering between lip color and skin color,a new method using perception learning algorithm base on penalty for lip positioning of color facial image.Experiments show that using perception approach for lip detection just sampling only once,it can attain the right threshold and can accurately detecte for all different lip pictures.Compared with the Fisher tra... |
