Abstract
The present invention discloses the detection of faces in digital images. Rather than subjecting the entire image (1) to computationally intensive face detection analysis, the image is instead segmented into regions (2) each of which has a substantially homogeneous color. Only those regions (2) having a predominantly skin color are then subjected to the face detection analysis. Preferably the face detection analysis is independent of facial color.
