ChildBot: Multi-Robot Perception and Interaction with Children

no code implementations28 Aug 2020 Niki Efthymiou, Panagiotis P. Filntisis, Petros Koutras, Antigoni Tsiami, Jack Hadfield, Gerasimos Potamianos, Petros Maragos

In this paper we present an integrated robotic system capable of participating in and performing a wide range of educational and entertainment tasks, in collaboration with one or more children.

A Deep Learning Approach to Object Affordance Segmentation

no code implementations18 Apr 2020 Spyridon Thermos, Petros Daras, Gerasimos Potamianos

In particular, we design an autoencoder that is trained using ground-truth labels of only the last frame of the sequence, and is able to infer pixel-wise affordance labels in both videos and static images.

Fusing Body Posture with Facial Expressions for Joint Recognition of Affect in Child-Robot Interaction

1 code implementation7 Jan 2019 Panagiotis P. Filntisis, Niki Efthymiou, Petros Koutras, Gerasimos Potamianos, Petros Maragos

In this paper we address the problem of multi-cue affect recognition in challenging scenarios such as child-robot interaction.

Deep Affordance-grounded Sensorimotor Object Recognition

no code implementations CVPR 2017 Spyridon Thermos, Georgios Th. Papadopoulos, Petros Daras, Gerasimos Potamianos

It is well-established by cognitive neuroscience that human perception of objects constitutes a complex process, where object appearance information is combined with evidence about the so-called object "affordances", namely the types of actions that humans typically perform when interacting with them.

A hierarchical approach with feature selection for emotion recognition from speech

no code implementations LREC 2012 Panagiotis Giannoulis, Gerasimos Potamianos

We examine speaker independent emotion classification from speech, reporting experiments on the Berlin database across six basic emotions.
