There is described a method for facial features detection in a picture frame containing a skin tone area, comprising dividing (12) the skin tone area into a number of parts; and for each part of the skin tone area, constructing (14) a luminance map, constructing an edge map by extracting (18) edges from the luminance map, defining (20) an edge magnitude threshold, building (22) a binary map from the edge map by keeping only the edges having a magnitude beyond the defined edge magnitude threshold and eliminating the others; and then extracting (24) facial features from the built binary map. An inter-related facial features detector is further described.
