Face Detection Algorithm Based On Skin Color Location

Face detection needs to locate the position of the face in an image before face recognition. In the paper, a face detection algorithm based on skin color location was presented for rapidly locating face position. Firstly, the actual obtained color images were converted into YCbCr and HSI space images. The numerical values of Cb and Cr image were rounded. A lot of spaces of background were eliminated with combining the thresholds of Cb, Cr, H and S. Secondly, the Cb and Cr values of the color part of the present image were counted, not more than two values of Cb and Cr were chosen respectively to jointly confirm skin color location. Finally, the luminance information image of the present location eliminated the pure skin color part such as hands to accurately locate face. The proposed algorithm can improve correct detection rate and reduce false detection rate to be beneficial to face detection.
