| 摘 要： | 针对人脸识别中的嘴部定位部分轮廓缺失问题,提出了一种由粗到精的快速准确的嘴部轮廓特征提取方法。该方法是在人脸检测的基础上采用改进的SUSAN算子提取嘴部边缘轮廓信息,通过几何特征和搜索区域相结合的方法实现了嘴唇轮廓的精确定位。仿真结果表明,该定位方法快速有效,正确率较高。

| Abstract: | For missing problem of partial contour of mouth positioning in face recognition, a rapid and exact method to extract the mouth contour feature from coarse to fine is proposed. On the basis of face detection, mouth edge profile information is extracted by the improved SUSAN operator. Combining with geometric features and searching area, the positioning of the mouth contour is accurately realized. Simulation results show that the mouth contour positioning method is fast and valid and has a high accuracy. |
