Detection and localization of facial profiles in color images

A novel coarse-to-fine facial profile detection and localization method in color images is proposed. First skin-tone regions are detected; Then removing some non-face regions by preprocessing rules; Thirdly the orientation of the facial profile is first detected, then extracting fiducial points on facial profile, finally these fiducial points are used to segment the facial profile based on the ratio relationship; At last final verification of the facial profiles is performed. Experiment results show the effectiveness of the proposed method.
