复杂背景下的人脸检测

Facial Detection in Complex Background

人脸检测作为人脸识别的关键,检测的精确度和速度直接影响人脸识别系统的性能。本文在肤色模型二值化、积分投影和分块计算LGBP直方图的基础上对复杂背景下的人脸进行检测,结果表明人脸检测不受光照、表情和遮挡物等的影响,提高了检测的正确率和运算速度。

Face detection as the key to face recognition, detection accuracy and speed directly affect the performance of face recognition system. Based on the binarization of the skin color model, the integral projection and the LGBP histogram, the face of the complex background is tested. The results show that the face detection is not affected by the light, the expression and the occlusion. The correct rate and the operation speed are improved.
