Color filtering-based efficient face detection

In this paper we propose a sub-window scanning method and a face/non-face classifier using a facial color filter. The scanning method skips over sub-windows that do not contain possible faces based on a facial color membership function. The face/non-face classifier using facial color has low computational cost and can reject non-face sub-windows in an early stage of the cascade face detector. The proposed model reduces the overall computation time of face detection and eliminates false alarms.
