On the performance of preconditioned methods to solve \(L^p\)-norm phase unwrapping
Ricardo Legarda-Saenz, Carlos Brito-Loeza, Arturo Espinosa-Romero
In this paper, we analyze and evaluate suitable preconditioning techniques to improve the performance of the -norm phase unwrapping method. We consider five preconditioning te…
Variational phase recovering without phase unwrapping in phase-shifting interferometry
Ricardo Legarda-Saenz, Alejandro Téllez Quiñones, Carlos Brito-Loeza +1
We present a variational method for recovering the phase term from the information obtained from phase-shifting methods. First we introduce the new method based on a variational ap…
Augmented Lagrangian method for a TV-based model for demodulating phase discontinuities
Ricardo Legarda-Saenz, Carlos Brito-Loeza
In this work we reformulate the method presented in App. Opt. 53:2297 (2014) as a constrained minimization problem using the augmented Lagrangian method. First we introduce the new…
