摘要
提出了一种利用24位彩色图像对嘴唇进行分割和提取的方法。首先，采用红色像素点进行水平和垂直投影的方法对嘴唇进行区域分割，然后再利用边缘提取和红色像素点提取相结合的方法对嘴唇进行提取，此方法可以有效地去除嘴唇周围的阴影干扰和其它干扰，完整地将嘴唇从原图中分割提取出来。
A method of segmenting and extracting the mouth from the facial image based on 24 bit color image is proposed.At first, the area of the mouth is segmented by using the value vertical and horizontal projection of red pixel. Then the mouth is extrated by using the method of edge extraction and red pixel extraction. This method can effectively erase the interference of the shade and other interferences, and extract the mouth from image.
