Illumination induced appearance changes represent one of the open challenges in automated face recognition systems still signi?cantly in?uencing their performance. In this paper we present a novel normalization scheme based on the nuisance attribute projection, which tries to remove the effects of illumination by projecting away multiple dimensions of a illumination subspace. The technique is assessed in face recognition experiments performed on the extended YaleB and XM2VTS databases. Comparative results with state-of-the-art techniques show the competitiveness of the proposed technique.

Subspace projection techniques are known to be susceptible to the presence of partial occlusions in the image. To overcome this susceptibility, we propose a confidence weighting scheme that assigns weights to pixels according to a measure, which quantifies the confidence that the pixel in question represents an outlier. The confidence weighting concept is further improved by a local procedure for the estimation of representation. Proposed procedures are assessed in recognition experiments on the occluded facial images in AR database with encouraging results.

In this thesis we tackle the problem of face recognition in uncontrolled conditions. The main topic of the thesis, is related to Gabor filters and robust recognition based on Gabor face representations. To improve upon the existing Gabor magnitude based methods, we propose a novel feature type derived from the Gabor phase. We demonstrate the robustness of the proposed technique in face recognition experiments on five experimental databases, namely, the XM2VTS, AR, FERET, BANCA and Extended Yale B databases. The experimental results clearly show the benefits of our approach.

This paper describes current research and applications on speech technologies for the Slovenian language, as well as the complexity and interdisciplinary nature of the problem. Importance of Slovenian language for our national identity and problems and achievements concerning implementation of speech technologies systems for Slovenian language is emphasized.

The European Union article argues that the multilingual nature of Europe can be enhanced through technology so long as lesser researched languages are not left behind. It may be true that multilingualism had become a policy at the European level, but it should continue to be promoted in education, training, and research programs, with a clear reminder that languages with a lower number of speakers are not left behind. We need to e-include not only the elderly and users with special needs, but also users who speak less-researched languages.
