MeshPose: Unifying DensePose and 3D Body Mesh reconstruction
Eric-Tuan Lê, Antonis Kakolyris, Petros Koutras +5
DensePose provides a pixel-accurate association of images with 3D mesh coordinates, but does not provide a 3D mesh, while Human Mesh Reconstruction (HMR) systems have high 2D repro…
ViDaS Video Depth-aware Saliency Network
Ioanna Diamanti, Antigoni Tsiami, Petros Koutras +1
We introduce ViDaS, a two-stream, fully convolutional Video, Depth-Aware Saliency network to address the problem of attention modeling ``in-the-wild", via saliency prediction in vi…
ChildBot: Multi-Robot Perception and Interaction with Children
Niki Efthymiou, Panagiotis P. Filntisis, Petros Koutras +4
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 m…
How to track your dragon: A Multi-Attentional Framework for real-time RGB-D 6-DOF Object Pose Tracking
Isidoros Marougkas, Petros Koutras, Nikos Kardaris +3
We present a novel multi-attentional convolutional architecture to tackle the problem of real-time RGB-D 6D object pose tracking of single, known objects. Such a problem poses mult…
STAViS: Spatio-Temporal AudioVisual Saliency Network
Antigoni Tsiami, Petros Koutras, Petros Maragos
We introduce STAViS, a spatio-temporal audiovisual saliency network that combines spatio-temporal visual and auditory information in order to efficiently address the problem of sal…
Deeply Supervised Multimodal Attentional Translation Embeddings for Visual Relationship Detection
Nikolaos Gkanatsios, Vassilis Pitsikalis, Petros Koutras +2
Detecting visual relationships, i.e. <Subject, Predicate, Object> triplets, is a challenging Scene Understanding task approached in the past via linguistic priors or spatial inform…
Fusing Body Posture with Facial Expressions for Joint Recognition of Affect in Child-Robot Interaction
Panagiotis P. Filntisis, Niki Efthymiou, Petros Koutras +2
In this paper we address the problem of multi-cue affect recognition in challenging scenarios such as child-robot interaction. Towards this goal we propose a method for automatic r…
SUSiNet: See, Understand and Summarize it
Petros Koutras, Petros Maragos
In this work we propose a multi-task spatio-temporal network, called SUSiNet, that can jointly tackle the spatio-temporal problems of saliency estimation, action recognition and vi…
A Deep Learning Approach for Multi-View Engagement Estimation of Children in a Child-Robot Joint Attention task
Jack Hadfield, Georgia Chalvatzaki, Petros Koutras +3
In this work we tackle the problem of child engagement estimation while children freely interact with a robot in their room. We propose a deep-based multi-view solution that takes…
LSTM-based Network for Human Gait Stability Prediction in an Intelligent Robotic Rollator
Georgia Chalvatzaki, Petros Koutras, Jack Hadfield +3
In this work, we present a novel framework for on-line human gait stability prediction of the elderly users of an intelligent robotic rollator using Long Short Term Memory (LSTM) n…
Multimodal Visual Concept Learning with Weakly Supervised Techniques
Giorgos Bouritsas, Petros Koutras, Athanasia Zlatintsi +1
Despite the availability of a huge amount of video data accompanied by descriptive texts, it is not always easy to exploit the information contained in natural language in order to…
Multimodal Signal Processing and Learning Aspects of Human-Robot Interaction for an Assistive Bathing Robot
A. Zlatintsi, I. Rodomagoulakis, P. Koutras +4
We explore new aspects of assistive living on smart human-robot interaction (HRI) that involve automatic recognition and online validation of speech and gestures in a natural inter…
