Synthetic Data for Multi-Parameter Camera-Based Physiological Sensing

no code implementations10 Oct 2021 Daniel McDuff, Xin Liu, Javier Hernandez, Erroll Wood, Tadas Baltrusaitis

We present systematic experiments showing how physiologically-grounded synthetic data can be used in training camera-based multi-parameter cardiopulmonary sensing.

DeepFN: Towards Generalizable Facial Action Unit Recognition with Deep Face Normalization

no code implementations3 Mar 2021 Javier Hernandez, Daniel McDuff, Ognjen, Rudovic, Alberto Fung, Mary Czerwinski

We show that person-independent models yield significantly lower performance (55% average F1 and accuracy across 40 subjects) than person-dependent models (60. 3%), leading to a generalization gap of 5. 3%.
