3D Facial expression recognition based on basic geometric features
Xiaoli Li,Qiuqi Ruan,Yue Ming +2 more
TL;DR: The facial feature vectors with the information of slopes and the angles as the feature vectors got from the facial feature points, not only the distance information mentioned in the previous work are added.
Journal ArticleDOI
Fully automatic 3D facial expression recognition using polytypic multi-block local binary patterns
TL;DR: A novel holistic, full-automatic approach for 3D facial expression recognition, namely polytypic multi-block local binary patterns (P-MLBP), which involves both the feature-based irregular divisions and the fusion of depth and texture information of 3D models to enhance facial feature.
Proceedings ArticleDOI
Efficient Kernel Discriminate Spectral Regression for 3D face recognition
TL;DR: A novel framework for 3D face recognition based on depth information, a method for utilizing a reproducing kernel Hubert space into which data points are mapped, which decreased the complexity from cubic-time to quadratic-time resulting in a very significant reduction in computation time.
Journal ArticleDOI
Multiple strategies to enhance automatic 3D facial expression recognition
TL;DR: The strategies of irregular division schemes and the entropy weighted blocks are employed to improve the recognition accuracy and draw a promising direction for automatic 3D facial expression recognition.
Journal ArticleDOI
A remarkable standard for estimating the performance of 3D facial expression features
Xiaoli Li,Qiuqi Ruan,Yue Ming +2 more
TL;DR: This paper verifies that the KL divergence can definitely be considered as the standard for determining the ''best'' features to recognize 3D facial expressions.
