Facial feature extraction and pose determination

摘要

A combined approach for facial feature extraction and determination of gaze direction is proposed that employs some improved variations of the adaptive Hough transform for curve detection, minima analysis of feature candidates, template matching for inner facial feature localization, active contour models for inner face contour detection and projective geometry properties for accurate pose determination. The aim is to provide a sufficient set of features for further use in a face recognition or face tracking system. (C) 2000 Pattern Recognition Society. Published by Elsevier Science Ltd.
