Human group activity recognition (GAR) has attracted significant attention from computer vision researchers due to its wide practical applications in security surveillance, social role …
We present a novel approach for detecting social interactions in a crowded scene by employing solely visual cues. The detection of social interactions in unconstrained scenarios …
The analysis of human activities is one of the most intriguing and important open issues for the automated video surveillance community. Since few years ago, it has been handled …
Abstract Group Activity Recognition detects the activity collectively performed by a group of actors, which requires compositional reasoning of actors and objects. We approach the task …
Computer vision plays an important role in the automated analysis of human groups. The appearance of human groups has been studied for various reasons, including detection …
In this paper, a new heat-map-based algorithm is proposed for group activity recognition. The proposed algorithm first models human trajectories as series of heat sources and then …
Interactive playgrounds are technology-enhanced installations that aim to provide rich game experiences for children by combining the benefits of traditional playgrounds with those of …
