Robust Regression
TL;DR: The theory of robust regression (RR) is developed and an effective convex approach that uses recent advances on rank minimization is presented that applies to a variety of problems in computer vision including robust linear discriminant analysis, regression with missing data, and multi-label classification.
Proceedings ArticleDOI
Unifying Nuclear Norm and Bilinear Factorization Approaches for Low-Rank Matrix Decomposition
TL;DR: A unified approach to bilinear factorization and nuclear norm regularization is proposed, that inherits the benefits of both and proposes a new optimization algorithm and a "rank continuation'' strategy that outperform state-of-the-art approaches for Robust PCA, Structure from Motion and Photometric Stereo with outliers and missing data.
Proceedings Article
Matrix Completion for Multi-label Image Classification
TL;DR: This paper formulates image categorization as a multi-label classification problem using recent advances in matrix completion and proposes two convex algorithms for matrix completion based on a Rank Minimization criterion specifically tailored to visual data, and proves its convergence properties.
Journal ArticleDOI
Matrix Completion for Weakly-Supervised Multi-Label Image Classification
TL;DR: Experimental validation on several data sets shows that the weakly-supervised system for multi-label image classification outperforms state-of-the-art classification algorithms, while effectively capturing each class appearance.
Proceedings ArticleDOI
Piecewise Planar and Compact Floorplan Reconstruction from Images
Ricardo Cabral,Yasutaka Furukawa +1 more
TL;DR: This paper presents a system to reconstruct piecewise planar and compact floorplans from images, which are then converted to high quality texture-mapped models for free- viewpoint visualization, and shows that the texture mapped mesh models provide compelling free-viewpoint visualization experiences, when compared against the state-of-the-art and ground truth.
