Beyond FACS: Data-driven Facial Expression Dictionaries, with Application to Predicting Autism
Evangelos Sariyanidi, Lisa Yankowitz, Robert T. Schultz +3
The Facial Action Coding System (FACS) has been used by numerous studies to investigate the links between facial behavior and mental health. The laborious and costly process of FAC…
3D Face Reconstruction Error Decomposed: A Modular Benchmark for Fair and Fast Method Evaluation
Evangelos Sariyanidi, Claudio Ferrari, Federico Nocentini +3
Computing the standard benchmark metric for 3D face reconstruction, namely geometric error, requires a number of steps, such as mesh cropping, rigid alignment, or point corresponde…
