Solving OSCAR regularization problems by proximal splitting algorithms
Xiangrong Zeng, Mário A. T. Figueiredo
The OSCAR (octagonal selection and clustering algorithm for regression) regularizer consists of a L_1 norm plus a pair-wise L_inf norm (responsible for its grouping behavior) and w…

Robust Periocular Recognition By Fusing Sparse Representations of Color and Geometry Information
Juan C. Moreno, V. B. S. Prasath, Gil Santos +1
In this paper, we propose a re-weighted elastic net (REN) model for biometric recognition. The new model is applied to data separated into geometric and color spatial components. T…

Brain MRI Segmentation with Fast and Globally Convex Multiphase Active Contours
Juan C. Moreno, V. B. S. Prasath, Hugo Proenca +1
Multiphase active contour based models are useful in identifying multiple regions with different characteristics such as the mean values of regions. This is relevant in brain magne…
