| 摘 要： | 基于人脸类似椭圆的特性,提出一种基于图像矩的驾驶员面部椭圆拟合定位方法.该方法利用肤色信息对驾驶室采集的彩色图像在颜色空间进行快速分割的基础上,利用图像矩拟合驾驶员面部椭圆,从而准确的定位跟踪驾驶员的位置,有效的降低了驾驶室的复杂背景、驾驶员各种面部姿态、表情对人脸检测定位的影响,同时也避免了常用椭圆拟合方法计算量大的不足.实验与仿真表明该方法具有快速、稳健和姿态不敏感的特性.

| Abstract: | A method of driver's face location is proposed based on image moments and ellipse fitting.Using skin color information in YCbCr space to segmentation and morphological pre-processing,the driver's facial features is similar to the ellipse.Combined with image moments to ellipse fitting an oval driver's face,accurate positioning to track the location of human face is acquired.Experiment and simulation show that the method is fast,robust and insensitive to the characteristics of gestures. |
