Feature and label relation modeling for multiple-facial action unit classification and intensity estimation

作者：

Highlights：

• We expoit the relations of AUs from both shared features and labels for AU analyses.

• A MTL is used to recognize multiple AUs or AU intensity simultaneously.

• A BN is used to model AUs relations from labels by structure and parameter learning.
