FaceRNET: a Facial Expression Intensity Estimation Network
share
This paper presents our approach for Facial Expression Intensity Estimation from videos. It includes two components: i) a representation extractor network that extracts various emotion descriptors (valence-arousal, action units and basic expressions) from each videoframe; ii) a RNN that captures temporal information in the data, followed by a mask layer which enables handling varying input video lengths through dynamic routing. This approach has been tested on the Hume-Reaction dataset yielding excellent results.
