Error concealment by means of motion refinement and regularized Bregman divergence
Alessandra M. Coelho, Vania V. Estrela, Felipe P. do Carmo +1
This work addresses the problem of error concealment in video transmission systems over noisy channels employing Bregman divergences along with regularization. Error concealment in…
EM-Based Mixture Models Applied to Video Event Detection
Alessandra Martins Coelho, Vania V. Estrela
Surveillance system (SS) development requires hi-tech support to prevail over the shortcomings related to the massive quantity of visual information from SSs. Anything but reduced…
Blind signal separation and identification of mixtures of images
Felipe P. do Carmo, Joaquim T. de Assis, Vania V. Estrela +1
In this paper, a fresh procedure to handle image mixtures by means of blind signal separation relying on a combination of second order and higher order statistics techniques are in…
State-of-the Art Motion Estimation in the Context of 3D TV
Vania V. Estrela, Alessandra M. Coelho
Progress in image sensors and computation power has fueled studies to improve acquisition, processing, and analysis of 3D streams along with 3D scenes/objects reconstruction. The r…
