Are 3D Face Shapes Expressive Enough for Recognising Continuous Emotions and Action Unit Intensities?
Are 3D Face Shapes Expressive Enough for Recognising Continuous Emotions and Action Unit Intensities?
Recognising continuous emotions and action unit (AU) intensities from face videos, requires a spatial and temporal understanding of expression dynamics. Existing works primarily rely on 2D face appearance features to extract such dynamics. This work focuses on a promising alternative based on parametric 3D face alignment models, which disentangle different …
