A fast algorithm for a total variation based phase demodulation model
In this paper we introduce fast numerical algorithms for the solution of the model [Total variation regularization cost function for demodulating phase discontinuities, Journal Applied Optics, 53(11):2297-2301, 2014]. For ... -

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 ... -

An automatic algorithm for the detection of Trypanosoma cruzi parasites in blood sample images
Chagas disease is a tropical parasitic disease caused by the flagellate protozoan Trypanosomacruzi (T. cruzi) and currently affecting large portions of the Americas. One of the standard laboratory methods to determine the ... -
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 ... -

Chagas Parasite Detection in Blood Images Using AdaBoost
The Chagas disease is a potentially life-threatening illness caused by the protozoan parasite, Trypanosoma cruzi. Visual detection of such parasite through microscopic inspection is a tedious and time-consuming task. In ... -
Chagas Parasites Detection through Gaussian Discriminant Analysis
Visual detection of Chagas parasites through microscopic inspection is a tedious and time-consuming task. In this paper we provide an algorithm based on Gaussian discriminant analysis for the task of Chagas parasites ... -
