A mean curvature regularized based model for demodulating phase maps from fringe patterns
We introduce a variational method for demodulating phase maps from fringe patterns. This new method is based on the mean curvature of the level sets of the phase surface that is used for regularization. The performance of ... -
Augmented Lagrangian method for a total variation-based model for demodulating phase discontinuities
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 method and then describe the numerical ... -
Image denoising using the Gaussian curvature of the image surface
A number of high-order variational models for image denoising have been proposed within the last few years. The main motivation behind these models is to fix problems such as the staircase effect and the loss of image ...
