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…
Stochastic Stability in Max-Product and Max-Plus Systems with Markovian Jumps
Ioannis Kordonis, Petros Maragos, George P. Papavassilopoulos
We study Max-Product and Max-Plus Systems with Markovian Jumps and focus on stochastic stability problems. At first, a Lyapunov function is derived for the asymptotically stable de…
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…
A Finite Element Computational Framework for Active Contours on Graphs
Nikolaos Kolotouros, Petros Maragos
In this paper we present a new framework for the solution of active contour models on graphs. With the use of the Finite Element Method we generalize active contour models on graph…
Online Wideband Spectrum Sensing Using Sparsity
Lampros Flokas, Petros Maragos
Wideband spectrum sensing is an essential part of cognitive radio systems. Exact spectrum estimation is usually inefficient as it requires sampling rates at or above the Nyquist ra…
