SPENCER: A Socially Aware Service Robot for Passenger Guidance and Help in Busy Airports
Rudolph Triebel,Kai O. Arras,Rachid Alami,Lucas Beyer,Stefan Breuers,Raja Chatila,Mohamed Chetouani,Daniel Cremers,Vanessa Evers,Michelangelo Fiore,Hayley Hung,Omar Adair Islas Ramirez,Michiel Joosse,Harmish Khambhaita,Tomasz Piotr Kucner,Bastian Leibe,Achim J.

TL;DR: How the SPENCER project advances the fields of detection and tracking of individuals and groups, recognition of human social relations and activities, normative human behavior learning, socially-aware task and motion planning, learning socially annotated maps, and conducting empirical experiments to assess socio-psychological effects of normative robot behaviors is described.

Structure Preserving Object Tracking
Lu Zhang,Laurens van der Maaten +1 more
TL;DR: The experimental evaluation of the structure-preserving object tracker (SPOT) reveals significant performance improvements in multi-object tracking and shows that SPOT can improve the performance of single-object trackers by simultaneously tracking different parts of the object.
Journal ArticleDOI
Preserving Structure in Model-Free Tracking
Lu Zhang,Laurens van der Maaten +1 more
TL;DR: The experimental evaluation of the structure-preserving object tracker (SPOT) reveals substantial performance improvements in multi-object tracking and shows that SPOT can be used to adapt generic, model-based object detectors during tracking to tailor them towards a specific instance of that object.
Proceedings ArticleDOI
Beyond F-Formations: Determining Social Involvement in Free Standing Conversing Groups from Static Images
Lu Zhang,Hayley Hung +1 more
TL;DR: This paper presents the first attempt to analyse differing levels of social involvement in free standing conversing groups (or the so-called F-formations) from static images and generates a richer model of the social interactions in a scene but also significantly improve F-formation detection.
Proceedings ArticleDOI
Speeding Up Tracking by Ignoring Features
TL;DR: The paper presents a new approach that limits the computational costs of trackers by ignoring features in image regions that -- after inspecting a few features -- are unlikely to contain the target object.
