Localized Global Descriptors for Image Retrieval: An Extensive Evaluation on Adaptations to the Simple Model

Anagnostopoulos, Nektarios; Iakovidou, Chrysanthi; Chatzichristofis, Savvas A.; Boutalis, Yiannis; Lux, Mathias (IEEE (Computer Society), 2016)

SIMPLE (Searching Images with MPEG-7 (& MPEG-7-like) Powered Localized dEscriptors) is a model that proposes the reuse of well-established global descriptors by localizing their description mechanism on image patches located ...
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 ...
