  • Text localization using standard deviation analysis of structure elements and support vector machines 

    Zagoris, Konstantinos; Chatzichristofis, Savvas A.; Papamarkos, Nikos (Springer, 2011)
    A text localization technique is required to successfully exploit document images such as technical articles and letters. The proposed method detects and extracts text areas from document images. Initially a connected ...

  • Towards a Parallel Inference Hnchine: the APIH project 

    Vlahavas, J.; Pombortsis, A.; Stamatis, D. (Microprocessing and Microprogmmmlng, 1990-08)
    This paper gives an overview of the APIM (Aristotle Parallel Inference Machine) research project, which aims to the design of a new multiprocessor architecture for the parallel execution of logic programs. The APIM system ...

  • Towards privacy in personal data management 

    Efraimidis, Pavlos S.; Drosatos, Georgios; Nalbadis, Fotis; Tasidou, Aimilia (2009)
    Purpose – In order to enhance privacy protection during electronic transactions, the purpose of this paper is to propose, develop, and evaluate a personal data management framework called Polis that abides by the following ...

  • User-Centric Privacy-Preserving Statistical Analysis of Ubiquitous Health Monitoring Data 

    Drosatos, George; Efraimidis, Pavlos S. (ComSIS Consortium, 2014)
    In this paper, we propose a user-centric software architecture for managing Ubiquitous Health Monitoring Data (UHMD) generated from wearable sensors in a Ubiquitous Health Monitoring System (UHMS), and examine how these ...

  • Versatile Query Scrambling for Private Web Search 

    Arampatzis, Avi; Drosatos, George; Efraimidis, Pavlos S. (Springer Link, 2015-05-16)
    We consider the problem of privacy leaks suffered by Internet users when they perform web searches, and propose a framework to mitigate them. In brief, given a ‘sensitive’ search query, the objective of our work is to ...

  • Vision-Controlled Micro Flying Robots: From System Design to Autonomous Navigation and Mapping in GPS-Denied Environments 

    Scaramuzza, Davide; Achtelik, Michael; Doitsidis, Lefteris; Fraundorfer, Friedrich; Kosmatopoulos, Elias; Martinelli, Agostino; Achtelik, Markus Wilhelm; Chli, Margarita; Chatzichristofis, Savvas A.; Kneip, Laurent; Gurdan, Daniel; Heng, Lionel; Lee, Gim Hee; Lynen, Simon; Meier, Lorenz; Pollefeys, Marc; Renzaglia, Alessandro; Siegwart, Roland; Stumpf, Jan Carsten; Tanskanen, Petri; Troiani, Chiara; Weiss, Stephan (IEEE, 2014)
    Autonomous micro helicopters are about to play a major role in tasks like search and rescue, environment monitoring, security surveillance, inspection, etc. If they are further realized in small scale, they can also be ...

  • Water Supply Optimization: An IPA Approach 

    Heracleous, Constantinos; Zinonos, Zinon; Panayiotou, Christos G. (Elsevier, 2014)
    In this paper we address the problem of deciding whether a water source should be used by a water utility such that the production cost as well as the penalty cost due to water shortages is minimized while certain ...

  • What, Where and How? Introducing pose manifolds for industrial object manipulation 

    Kouskouridas, R.; Amanatiadis, A.; Chatzichristofis, Savvas A.; Gasteratos, A. (Elsevier, 2015)
    In this paper we propose a novel method for object grasping that aims to unify robot vision techniques for 24 efficiently accomplishing the demanding task of autonomous object manipulation. Through ontological 25 concepts, ...

  • Wireless sensor networks mobility management using fuzzy logic 

    Zinonos, Zinon; Chrysostomou, Chrysostomos; Vassiliou, Vasos (Elsevier, 2014)
    This paper presents a novel, intelligent controller to support mobility in wireless sensor networks. In particular, the focus is on the deployment of such mobility solution to critical applications, like personnel safety ...
