HANG Fei, LIU Huiyi. A New Method for Face Pose Interaction in Virtual Environment[J]. Journal of Image and Graphics, 2010, 15(8): 1145. DOI: 10.11834/jig.20100817.
A new method is proposed for face pose estimation based on the area ratio in the paper. First
the change of triangle area ratio which consist of feature points is analyzed when a face turns. Then
the BP neural network is applied to train the relationship between position parameters of area ratio of face and the parameters of pose for face pose estimation. Finally
the method is applied to roam in the virtual environment. The experimental results demonstrate that this method can estimate accurately pose using only few characteristic points
and also does well in recognition rate and stability.
