Learning Multi-dimensional Edge Feature-based AU Relation Graph for Facial Action Unit Recognition. (arXiv:2205.01782v1 [cs.CV])

The activations of Facial Action Units (AUs) mutually influence one another.
While the relationship between a pair of AUs can be complex and unique,
existing approaches fail to specifically and explicitly represent such cues for
each pair of AUs in each facial display. This paper proposes an AU relationship
modelling approach that deep learns a unique graph to explicitly describe the
relationship between each pair of AUs of the target facial display. Our
approach first encodes each AU's activation status …
