Copula Ordinal Regression for Joint Estimation of Facial Action Unit Intensity
2016
2016 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)
Joint modeling of the intensity of facial action units (AUs) from face images is challenging due to the large number of AUs (30+) and their intensity levels (6). This is in part due to the lack of suitable models that can efficiently handle such a large number of outputs/classes simultaneously, but also due to the lack of labelled target data. For this reason, majority of the methods proposed so far resort to independent classifiers for the AU intensity. This is suboptimal for at least two
