Analysis of Social Scenes from Multimodal Data



Automated analysis of interactions in social scenes is critical for a number of applications such as surveillance, robotics and social signal processing. In this project we focus on the analysis of conversational groups and we address different tasks (e.g. human tracking, head and body pose estimation, F-formation detection) processing multimodal data gathered from camera networks and wearable sensors.
