| 摘 要： | 提出并实现了一种新的提取人脸封闭轮廓的方法.首先通过三目立体视觉系统获得彩色图和深度图,然后利用彩色图的肤色信息和深度图的深度信息而惟一确定的面部区域,最后再通过对面部肤色区域轮廓提取并结合活动轮廓模型(Snake)提取下巴,从而完成整个人脸轮廓的提取.该算法能够较好地提取人脸的轮廓线,克服了下巴边界难以从颈部区域提出的困难,定位精度高,边缘连续性好,满足了人脸轮廓特征提取的要求.

| Abstract: | This paper proposes a new method for face contour extraction.Triclops Stereo Vision System is used to get color images and depth images.Then,we make use of skin luma in color images and depth information in depth images to get the face area.Finally,we extract the whole face contour by extracting upper face contour in the face region through skin color model and extracting chin contour through active contour model(Snake).This algorithm can get rid of the trouble that chin contour is hardly extracted from the neck area,robustly extract face contour with high precision and satisfy the demand of face contour feature extraction. |
