Facial Expression Recognition Based on Feature Regions Automatic Segmentation

To improve 3D facial expression feature regions segmentation,an automatic feature regions segmentation method is presented.The facial feature points are detected by conducting projection and curvature calculation,and are used as the basis of facial expression feature regions automatic segmentation.To obtain more abundant facial expression information,the Facial Action Coding System(FACS) coding rules is introduced to extend the extracted characteristic matrix.And facial expressions can be recognized by combining classifiers.Experimental results of 3D facial expression samples show that the method is effective with high recognition rate.
