Enhancing Handwritten Text Recognition with N-gram sequence decomposition and Multitask Learning
Vasiliki Tassopoulou, George Retsinas, Petros Maragos
Current state-of-the-art approaches in the field of Handwritten Text Recognition are predominately single task with unigram, character level target units. In our work, we utilize a…
Sparse Approximate Solutions to Max-Plus Equations with Application to Multivariate Convex Regression
Nikos Tsilivis, Anastasios Tsiamis, Petros Maragos
In this work, we study the problem of finding approximate, with minimum support set, solutions to matrix max-plus equations, which we call sparse approximate solutions. We show how…
Independent Sign Language Recognition with 3D Body, Hands, and Face Reconstruction
Agelos Kratimenos, Georgios Pavlakos, Petros Maragos
Independent Sign Language Recognition is a complex visual recognition problem that combines several challenging tasks of Computer Vision due to the necessity to exploit and fuse in…
Advances in the training, pruning and enforcement of shape constraints of Morphological Neural Networks using Tropical Algebra
Nikolaos Dimitriadis, Petros Maragos
In this paper we study an emerging class of neural networks based on the morphological operators of dilation and erosion. We explore these networks mathematically from a tropical g…
Identifying differences in physical activity and autonomic function patterns between psychotic patients and controls over a long period of continuous monitoring using wearable sensors
Panagiotis P. Filntisis, Athanasia Zlatintsi, Niki Efthymiou +5
Digital phenotyping is a nascent multidisciplinary field that has the potential to revolutionize psychiatry and its clinical practice. In this paper, we present a rigorous statisti…
Emotion Understanding in Videos Through Body, Context, and Visual-Semantic Embedding Loss
Panagiotis Paraskevas Filntisis, Niki Efthymiou, Gerasimos Potamianos +1
We present our winning submission to the First International Workshop on Bodily Expressed Emotion Understanding (BEEU) challenge. Based on recent literature on the effect of contex…
Multiscale Fractal Analysis on EEG Signals for Music-Induced Emotion Recognition
Kleanthis Avramidis, Athanasia Zlatintsi, Christos Garoufis +1
Emotion Recognition from EEG signals has long been researched as it can assist numerous medical and rehabilitative applications. However, their complex and noisy structure has prov…
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…
WSRNet: Joint Spotting and Recognition of Handwritten Words
George Retsinas, Giorgos Sfikas, Petros Maragos
In this work, we present a unified model that can handle both Keyword Spotting and Word Recognition with the same network architecture. The proposed network is comprised of a non-r…
Weight Pruning via Adaptive Sparsity Loss
George Retsinas, Athena Elafrou, Georgios Goumas +1
Pruning neural networks has regained interest in recent years as a means to compress state-of-the-art deep neural networks and enable their deployment on resource-constrained devic…
Orientation Attentive Robotic Grasp Synthesis with Augmented Grasp Map Representation
Georgia Chalvatzaki, Nikolaos Gkanatsios, Petros Maragos +1
Inherent morphological characteristics in objects may offer a wide range of plausible grasping orientations that obfuscates the visual learning of robotic grasping. Existing grasp…
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…
