Can Facial Pose and Expression Be Separated With Weak Perspective Camera?

CVPR 2020poster

Separating facial pose and expression within images requires a camera model for 3D-to-2D mapping. The weak perspective (WP) camera has been the most popular choice; it is the default, if not the only option, in state-of-the-art facial analysis methods and software. WP camera is justified by the supp…

Discovering Synchronized Subsets of Sequences: A Large Scale Solution

CVPR 2020poster

Finding the largest subset of sequences (i.e., time series) that are correlated above a certain threshold, within large datasets, is of significant interest for computer vision and pattern recognition problems across domains, including behavior analysis, computational biology, neuroscience, and fina…

Inequality-Constrained and Robust 3D Face Model Fitting

ECCV 2020poster

Fitting 3D morphable models (3DMMs) on faces is a well-studied problem, motivated by various industrial and research applications. 3DMMs express a 3D facial shape as a linear sum of basis functions. The resulting shape, however, is a plausible face only when the basis coefficients take values within…
