| 摘 要： | 针对复杂背景的人脸彩色图像进行特征定位,一直是研究的热点和难点问题.提出了一种实时进行人脸特征定位的算法.在单人脸头肩图像序列中,首先利用背景差分法提取出人脸前景图像,利用几何先验知识和积分投影法分离出人脸区域;接着在人脸区域中采用YCbCr肤色模型、模板匹配以及边缘检测的方法定位出眼睛和嘴角,最后在RGB空间上采用阈值方法和积分投影法相结合的方法确定眉毛和鼻子的位置.实验表明,系统可以快速地检测出人脸特征,具有较高的检测精度和鲁棒性,检测的帧率达到10fps.

| Abstract: | Facial feature location in color image with complex background has been the hot spot and tough problem in the research field.This paper presents an algorithm for locating facial feature localization simultaneously.In sequences of image with one-head-shoulder,the foreground image is firstly extracted by an improved background differencing method,and then the face region can be acquired by prior knowledge and integration projection.Secondly a method that includes YCbCr human skin model,template matching and e... |
