Biosketch

Petros Koutras was born in Athens in 1987. He received the Diploma degree in Electrical and Computer Engineering from National Technical University of Athens in July 2012. His diploma thesis, supervised by Prof. Petros Maragos, was in estimation of Eye Gaze and emotion classification based on Active Appearance Models and using Geometrical and Pattern Recognition techniques.

Petros is currently a PhD student in the CVSP Group, school of ECE, NTUA, under the supervision of Prof. Petros Maragos, working in the general area of Computer Vision and its applications. His research interests lie primary in the field of Face Modeling, Visual Saliency and Event Detection.
