Title: Improving Face Analysis Using Expression Dynamics
Speaker: Hamdi Dibeklioğlu
Date/Time: Friday, June 26, 13:40-14:30
Place: FENS G032
Abstract: Most of the approaches in face analysis rely solely on static appearance. However, temporal analysis of expressions reveals interesting patterns. In this talk, I will describe automatic spontaneity detection for human smiles using facial dynamics. We have recorded spontaneous and posed enjoyment smiles of hundreds of visitors to the NEMO Science Centre in Amsterdam, thus creating the most comprehensive smile database ever: the UvA-NEMO Smile Database (www.uva-nemo.org). Our findings on this publicly available database show that facial dynamics go beyond expression analysis. I will discuss how we can use expression dynamics to improve age estimation, kinship verification, and assessment of depression severity.
