Fast L1-NMF for Multiple Parametric Model Estimation
Mariano Tepper, Guillermo Sapiro
In this work we introduce a comprehensive algorithmic pipeline for multiple parametric model estimation. The proposed approach analyzes the information produced by a random samplin…
Nonnegative Matrix Underapproximation for Robust Multiple Model Fitting
Mariano Tepper, Guillermo Sapiro
In this work, we introduce a highly efficient algorithm to address the nonnegative matrix underapproximation (NMU) problem, i.e., nonnegative matrix factorization (NMF) with an add…
A Bi-clustering Framework for Consensus Problems
Mariano Tepper, Guillermo Sapiro
We consider grouping as a general characterization for problems such as clustering, community detection in networks, and multiple parametric model estimation. We are interested in…
Video Human Segmentation using Fuzzy Object Models and its Application to Body Pose Estimation of Toddlers for Behavior Studies
Thiago V. Spina, Mariano Tepper, Amy Esler +4
Video object segmentation is a challenging problem due to the presence of deformable, connected, and articulated objects, intra- and inter-object occlusions, object motion, and poo…
Computer vision tools for the non-invasive assessment of autism-related behavioral markers
Jordan Hashemi, Thiago Vallin Spina, Mariano Tepper +4
The early detection of developmental disorders is key to child outcome, allowing interventions to be initiated that promote development and improve prognosis. Research on autism sp…
On the Role of Contrast and Regularity in Perceptual Boundary Saliency
Mariano Tepper, Pablo Musé, Andrés Almansa
Mathematical Morphology proposes to extract shapes from images as connected components of level sets. These methods prove very suitable for shape recognition and analysis. We prese…
