Quiroga Mellado, Juan Antonio ; Villa Hernández, José de Jesús ; Rodríguez-Vera, Ramón ; Rosa Vargas, José Ismael de la ; González Ramírez, Efrén | Elsevier Sci. Ltd. | 2010-06In our recently reported work [1] (Villa et al., 2009) we derived a regularized quadratic-cost function, which includes fringe orientation information, for denosing fringe pattern images. In this work we adopt such idea for denoising wrapped pha[...]texto impreso
Quiroga Mellado, Juan Antonio ; Villa Hernández, José de Jesús ; Servín Guirado, Manuel ; Estrada, Julio César ; Rosa Vargas, José Ismael de la | The Optical Society Of America | 2010-08-02It has been demonstrated that the vectorial fringe-direction field is very important to demodulate fringe patterns without a dominant (or carrier) frequency. Unfortunately, the computation of this direction-filed is by far the most difficult tas[...]texto impreso
Quiroga Mellado, Juan Antonio ; Villa Hernández, José de Jesús ; Rosa Vargas, José Ismael de la | Alan E. Willner, University of Southern California | 2009-06-01We use the regularization theory in a Bayesian framework to derive a quadratic cost function for denoising fringe patterns. As prior constraints for the regularization problem, we propose a Markov random field model that includes information abo[...]
