A survey on Graph Deep Representation Learning for Facial Expression Recognition
It synthesizes existing methods for researchers in facial expression recognition, but is incremental as a review paper.
This survey paper reviews graph representation learning methodologies for facial expression recognition, examining approaches like graph diffusion and spatio-temporal graphs while identifying future research directions.
This comprehensive review delves deeply into the various methodologies applied to facial expression recognition (FER) through the lens of graph representation learning (GRL). Initially, we introduce the task of FER and the concepts of graph representation and GRL. Afterward, we discuss some of the most prevalent and valuable databases for this task. We explore promising approaches for graph representation in FER, including graph diffusion, spatio-temporal graphs, and multi-stream architectures. Finally, we identify future research opportunities and provide concluding remarks.
