In this paper, we address the problem of detecting and learning socio-spatial relations between individuals and to track their group formations. ...
Detecting and tracking people and groups of people is a key skill for robots in populated environments. ...
A social network graph is built over time from observations of interacting individuals. Social relations between persons in overhead video data are recognized by Pellegrini et al. [14] . ...

However, little attention has been paid to analysing the affect expressed by a group of people in a scene or an interaction setting, either in the form of the individual group member's affect or the overall ...
In this paper, we (i) introduce a framework for analysing an image that contains multiple people and recognizing the arousal and valence expressed at the group-level; (ii) present a dataset of images annotated ...
