Roughness regularization for functional data analysis with free knots spline estimation
Anna De Magistris, Valentina De Simone, Elvira Romano +1
In the era of big data, an ever-growing volume of information is recorded, either continuously over time or sporadically, at distinct time intervals. Functional Data Analysis (FDA)…
Cartoon-texture evolution for two-region image segmentation
Laura Antonelli, Valentina De Simone, Marco Viola
Two-region image segmentation is the process of dividing an image into two regions of interest, i.e., the foreground and the background. To this aim, Chan et al. [Chan, Esedoglu, N…
Sparse Approximations with Interior Point Methods
Valentina De Simone, Daniela di Serafino, Jacek Gondzio +2
Large-scale optimization problems that seek sparse solutions have become ubiquitous. They are routinely solved with various specialized first-order methods. Although such methods a…
A view of computational models for image segmentation
Laura Antonelli, Valentina De Simone, Daniela di Serafino
Image segmentation is a central topic in image processing and computer vision and a key issue in many applications, e.g., in medical imaging, microscopy, document analysis and remo…
Updating constraint preconditioners for KKT systems in quadratic programming via low-rank corrections
S. Bellavia, V. De Simone, D. di Serafino +1
This work focuses on the iterative solution of sequences of KKT linear systems arising in interior point methods applied to large convex quadratic programming problems. This task i…
