In this paper we present our contribution to the MediaEval 2015 Retrieving Diverse Social Images Task which requested participants to provide methods for refining Flickr image retrieval results thus to increase their relevance and diversification. Our approach is based on re-ranking the original result, using a precomputed distance matrix and a spectral(More)
Inorganic based optical transducers have demonstrated their suitability for labelled and label-free sensing of biomolecules but suffer from their relatively high cost. Photonic structures fabricated in polymer by molding techniques could drastically reduce the cost per test and pave the way for label-free screening in point-of care environment where the(More)
In this paper we introduce a refinement and diversification process for re-ranking image search results based on social metadata and visual characteristics of the photos. The goal of the developed re-ranking algorithm is to construct a new sequence with maximal value of the harmonic mean of precision and diversity. Our contribution is twofold: estimation of(More)
We investigated different optical models (one-layer, multilayer, parametric multilayer, and statistical parametric) for the ellipsometric characterization of thin films made of silica spheres in the diameter (D) range of 90-450 nm prepared by the Langmuir-Blodgett (LB) technique. As a continuation of a previous work (Nagy, N., et al. Langmuir 2006, 22,(More)
