基于3×3块梯度图像划分和人脸几何模型的人脸检测

摘要

提出一个人脸检测算法，该算法使用3×3块划分的梯度图像和几何人脸模型来进行人脸检测.3×3块划分用来初步检测特定区域中是否有人脸，接下来利用几何人脸模型把人脸检测出来.实验结果表明所提出的人脸检测算法检测结果比较好，并且对于光照并不敏感.%This paper presents a face detection algorithm, the algorithm uses a gradient image of 3 Í3 block partition and geometric human face model for face detection. 3 Í 3 block partition is used to and preliminary detect whether someone in the specific area of the face, followed by the use of geometric face model face detection. The experimental results show that the proposed face detection algorithms to detect better results,and is not sensitive to light.
