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…
Sub-pixel accuracy edge fitting by means of B-spline
R. L. B. Breder, Vania V. Estrela, J. T. de Assis
Local perturbations around contours strongly disturb the final result of computer vision tasks. It is common to introduce a priori information in the estimation process. Improvemen…
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…
