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…
Estimating motion with principal component regression strategies
Felipe P. do Carmo, Vania Vieira Estrela, Joaquim Teixeira de Assis
In this paper, two simple principal component regression methods for estimating the optical flow between frames of video sequences according to a pel-recursive manner are introduce…
Content Based Image Retrieval (CBIR) in Remote Clinical Diagnosis and Healthcare
Albany E. Herrmann, Vania Vieira Estrela
Content-Based Image Retrieval (CBIR) locates, retrieves and displays images alike to one given as a query, using a set of features. It demands accessible data in medical archives a…
Expectation-Maximization Technique and Spatial-Adaptation Applied to Pel-Recursive Motion Estimation
Vania Vieira Estrela, Marcos Henrique da Silva Bassani
Pel-recursive motion estimation isa well-established approach. However, in the presence of noise, it becomes an ill-posed problem that requires regularization. In this paper, motio…
