  • Searching Images with MPEG-7 (& MPEG-7-like) Powered Localized dEscriptors: The SIMPLE answer to effective Content Based Image Retrieval 

    Iakovidou, Chrysanthi; Anagnostopoulos, Nektarios; Kapoutsis, Athanasios Ch.; Boutalis, Yiannis (IEEE (Computer Society), 2014)
    In this paper we propose and evaluate a new technique that localizes the description ability of the well established MPEG-7 and MPEG-7-like global descriptors. We employ the SURF detector to define salient image patches ...

  • Selection of the Proper Compact Composite Descriptor for Improving Content based Image Retrieval 

    Chatzichristofis, Savvas A.; Boutalis, Yiannis; Lux, Mathias (ACTA Press, Canada, 2009)

    Efraimidis, P.S.; Drosatos, G.; Nalbadis, F.; Tasidou, A. (Panhellenic Conference on Informatics, 2008-08-05)
    We present a personal data management framework called Polis, which abides by the following principle: Every individual has absolute control over her personal data, which reside only at her own side. Preliminary results ...

  • The TREC files: the (ground) truth is out there 

    Chatzichristofis, Savvas A.; Zagoris, Konstantinos; Arampatzis, Avi (Association for Computing Machinery (ACM), United States, 2011)
    Traditional tools for information retrieval (IR) evaluation, such as TREC’s trec_eval, have outdated command-line interfaces with many unused features, or ‘switches’, accumulated over the years. They are usually seen ...

  • Two-Staged Image Colorization Based on Salient Contours 

    Anagnostopoulos, Nektarios; Iakovidou, Chrysanthi; Amanatiadis, A.; Boutalis, Yiannis; Chatzichristofis, Savvas A. (IEEE (Computer Society), 2014)
    In this paper we present a novel colorization technique that manages to significantly reduce color bleeding artifacts caused by weak object boundaries and also requires only abstract color indications and placement from ...

  • A Versatile Tool for Privacy-Enhanced Web Search 

    Arampatzis, Avi; Drosatos, George; Efraimidis, Pavlos S. (European Conference on Information Retrieval, 2013)
    We consider the problem of privacy leaks suffered by Internet users when they perform web searches, and propose a framework to mitigate them. Our approach, which builds upon and improves recent work on search privacy, ...

  • Video Summarization Using a Self-Growing and Self-Organized Neural Gas Network 

    Papadopoulos, Dim. P.; Papamarkos, Nikos (Springer, 2011)
