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

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

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