Greek Sign Language Recognition for the SL-ReDu Learning Platform

no code implementations SLTAT (LREC) 2022 Katerina Papadimitriou, Gerasimos Potamianos, Galini Sapountzaki, Theodore Goulas, Eleni Efthimiou, Stavroula-Evita Fotinea, Petros Maragos

There has been increasing interest lately in developing education tools for sign language (SL) learning that enable self-assessment and objective evaluation of learners’ SL productions, assisting both students and their instructors.

Multimodal Locally Enhanced Transformer for Continuous Sign Language Recognition

no code implementations Conference of the International Speech Communication Association (INTERSPEECH) 2023 Katerina Papadimitriou, Gerasimos Potamianos

In this paper, we propose a novel Transformer-based approach for continuous sign language recognition (CSLR) from videos, aiming to address the shortcomings of traditional Transformers in learning local semantic context of SL.

Sign Language Recognition via Deformable 3D Convolutions and Modulated Graph Convolutional Networks

no code implementations IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP) 2023 Katerina Papadimitriou, Gerasimos Potamianos

Automatic sign language recognition (SLR) remains challenging, especially when employing RGB video alone (i. e., with no depth or special glove-based input) and under a signer-independent (SI) framework, due to inter-personal signing variation.

Accurate and Resource-Efficient Lipreading with Efficientnetv2 and Transformers

no code implementations ICASSP 2022 Alexandros Koumparoulis, Gerasimos Potamianos

We present a novel resource-efficient end-to-end architecture for lipreading that achieves state-of-the-art results on a popular and challenging benchmark.

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.
