A method of face detection is proposed,which is based on the skin information and improved local binary pattern(LBP).Firstly,the color of the input picture is compensated by using a novel illumination compensation method and the skin pixels are segmented.Secondly,the possible face areas are extracted by frontal face filter windows and the LBP features of them are obtained by an improved LBP operator.Lastly,the Mahalanobis distance is used to verify and locate the face by comparing the LBP histograms of poss...
