Kewei Shi, Fu Xitian, Cai An-ni, Sun Jing-ao · 1999
This paper presents a novel technique to automatically detect the human face in videophone images with YCrCb format. By using the Cr-Cb histogram to eliminate the background, and applying region growing in the remaining areas, we can, with the aid of the proposed criteria, accurately detect the face from a complex background.
