Panagiotis P. Filntisis

I am a PostDoctoral researcher at the National Technical University of Athens under the supervision of Prof. Petros Maragos. I am also a research associate at the Athena Research and Innovation Center. I work at the crossroads of computer vision and audio processing for affective computing. Some of my most recent endeavors include body emotion recognition, visual emotion translation, and 3D visual speech-aware facial expression reconstruction.
