A variational model for wrapped phase denoising
Ivan May-Cen, Ricardo Legarda-Saenz, Carlos Brito-Loeza
In this paper, we introduce a total variation based variational model for denoising wrapped phase images. Our model improves on former methods by preserving discontinuities of the…
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…
A novel variational model for image registration using Gaussian curvature
Mazlinda Ibrahim, Ke Chen, Carlos Brito-Loeza
Image registration is one important task in many image processing applications. It aims to align two or more images so that useful information can be extracted through comparison,…
