Abstract: Face detection in complicated backgrounds and different illumination conditions is one of the important problems to be solved in the automatic face recognition system.The image including faces is searched by using YCbCr color space firstly,then,the features of the segmented skin color areas are extracted through LSMQT method,further,the SNoW classifier is introduced.Finally,the features and classifier are combined for the task of face detection.The results of experiments show that this method has a high face detection correct rate to the images with complicated backgrounds and different illumination conditions.

Key words: face detection, YCbCr color space, Successive Mean Quantization Transform(SMQT), Sparse Network of Winnows(SNoW)

摘要: 复杂背景和光照多变的人脸检测是自动人脸识别系统需要解决的重要问题之一,首先利用YCbCr空间进行肤色分割,获取候选人脸区域,然后提取相应区块的LSMQT特征,并利用SNoW分类器进行特征分类,最终获取人脸在图像中的准确位置。实验证明,该方法对复杂背景和光照多变的图像中的人脸具有较高的正确检测率。
