Active contour model for extracting human faces
Takamichi Yokoyama, Yasushi Yagi, M. Yachida · 2002
In this paper, we propose a facial contour extraction model. The influence of environmental changes on the model is small, and it is based on an active contour model (ACM). Our method has three characteristics: global shape constraint of axis-symmetry, dual-scale filtering and iterative initialization. We apply the method to real human faces of more than 60 people with our face recognition system for evaluating effectiveness.
