On-the-fly Approximation of Multivariate Total Variation Minimization
Jordan Frecon, Nelly Pustelnik, Patrice Abry +1
In the context of change-point detection, addressed by Total Variation minimization strategies, an efficient on-the-fly algorithm has been designed leading to exact solutions for u…
Combining local regularity estimation and total variation optimization for scale-free texture segmentation
Nelly Pustelnik, Herwig Wendt, Patrice Abry +1
Texture segmentation constitutes a standard image processing task, crucial to many applications. The present contribution focuses on the particular subset of scale-free textures an…
A Proximal Approach for Sparse Multiclass SVM
G. Chierchia, Nelly Pustelnik, Jean-Christophe Pesquet +1
Sparsity-inducing penalties are useful tools to design multiclass support vector machines (SVMs). In this paper, we propose a convex optimization approach for efficiently and exact…
