摘要
提出了一种基于肤色的精确人脸定位算法,详细叙述了在图片的颜色调整与肤色检测,肤色区域的平滑、分割与填充,候选眼睛的选取及配对中遇到的具体问题并提出了解决方案.本算法能较为准确地定位彩色图像中的正面、小角度偏侧和旋转的人脸,还能检测出一幅图中的多个人脸.
Human faces need to be detected and segmented from the input images so can the system recognize them. The human face detection technology is discussed in detail.The method is based on the skin color and the facial features of human beings, and the difficulties and trend of the detection and recognition technology are expounded too. It can detect faces up-right or rotated with little angle in a single color image. Moreover it can detect multiple faces in the images correctly.
