  • CoMo: A Compact Composite Moment-Based Descriptor for Image Retrieval 

    Vassou, Sotiris A.; Anagnostopoulos, Nektarios; Amanatiadis, Angelos; Christodoulou, Klitos; Chatzichristofis, Savvas A. (ACM, 2017-06-19)
    Low level features play a vital role in image retrieval. Image moments can effectively represent global information of image content while being invariant under translation, rotation, and scaling. This paper briefly presents ...

  • How Smart Are Smartphones?: Bridging the marketing and information technology gap. 

    Amanatiadis, Angelos; Chatzichristofis, Savvas A. (IEEE, 2014)
    The term "smart" has become widespread in consumer electronics in recent years, reflecting the consumers' need for devices that assist them in their daily activities. The term has a long history of usage in marketing science ...

  • Image Moment Invariants as Local Features for Content Based Image Retrieval using the Bag-of-Visual-Words Model 

    Karakasis, Evangelos G.; Amanatiadis, Angelos; Gasteratos, Antonios; Chatzichristofis, Savvas A. (Elsevier, 2015)
    This paper presents an image retrieval framework that uses affine image moment invariants as descriptors of local image areas. Detailed feature vectors are generated by feeding the produced moments into a Bag-of-Visual-Words ...

  • A LoCATe‐based visual place recognition system for mobile robotics and GPGPUs 

    Bampis, Loukas; Chatzichristofis, Savvas A.; Iakovidou, Chryssanthi; Gasteratos, Antonios; Boutalis, Yiannis; Amanatiadis, Angelos (John Wiley & Sons Ltd, 2017-05)
    In this paper, a novel visual Place Recognition approach is evaluated based on a visual vocabulary of the Color and Edge Directivity Descriptor (CEDD) to address the loop closure detection task. Even though CEDD was initially ...

  • Real-time indexing for large image databases: color and edge directivity descriptor on GPU 

    Bampis, Loukas; Iakovidou, Chryssanthi; Chatzichristofis, Savvas A.; Boutalis, Yiannis S.; Amanatiadis, Angelos (Springer, 2014)
    In this paper, we focus on implementing the extraction of a well-known low-level image descriptor using the multicore power provided by general-purpose graphic processing units (GPGPUs). The color and edge directivity ...
