  • Color and Edge Directivity Descriptor on GPGPU 

    Iakovidou, Chrysanthi; Bampis, L.; Chatzichristofis, Savvas A.; Boutalis, Yiannis; Amanatiadis, A. (IEEE (Computer Society), 2015)
    Image indexing refers to describing the visual multimedia content of a medium, using high level textual information or/and low level descriptors. In most cases, images and videos are associated with noisy and incomplete ...

  • 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 ...

  • 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 ...
