基于区域生长分水岭算法嘴唇轮廓的提取

A region growing watershed algorithm-based algorithm for lips contour extraction

嘴唇是人脸部的重要特征,对嘴唇轮廓的提取有着非常重要的应用价值.本文针对彩色的嘴唇图像,采用基于区域生长的分水岭算法对嘴唇的轮廓进行提取.算法首先通过RGB三个分量,进行灰度转换,之后对图像采用区域生长算法进行处理,然后用中值滤波进行去噪和平滑处理,最后,应用分水岭算法得到嘴唇的轮廓.实验证明,此方法实现简单,达到了预期效果,性能良好.

The lips are an important feature of human face, lips contour extraction has a very important application value. In this paper, a region growing - based watershed algorithm is proposed to extract the contours of the lips. Firstly, the three RGB components are converted into grayscale; Then, conduct region growing algorithm on the images, and perform median fikering for de - noising and smoothing, and finally, by applying the watershed algorithm to detect lip contours. Experimental results show that this method is simple, and achieve the desired effect, and excellent performance.
