From Categories to Subcategories: Large-Scale Image Classification With Partial Class Label Refinement

no code implementations CVPR 2015 Marko Ristin, Juergen Gall, Matthieu Guillaumin, Luc van Gool

Compared to approaches that disregard the extra coarse labeled data, we achieve a relative improvement in subcategory classification accuracy of up to 22% in our large-scale image classification experiments.

Quantized Kernel Learning for Feature Matching

no code implementations NeurIPS 2014 Danfeng Qin, Xuanli Chen, Matthieu Guillaumin, Luc V. Gool

Matching local visual features is a crucial problem in computer vision and its accuracy greatly depends on the choice of similarity measure.

Closed-Form Training of Conditional Random Fields for Large Scale Image Segmentation

no code implementations27 Mar 2014 Alexander Kolesnikov, Matthieu Guillaumin, Vittorio Ferrari, Christoph H. Lampert

It is inspired by existing closed-form expressions for the maximum likelihood parameters of a generative graphical model with tree topology.

Fast Energy Minimization Using Learned State Filters

no code implementations CVPR 2013 Matthieu Guillaumin, Luc van Gool, Vittorio Ferrari

However, when the graph is fully connected and the pairwise potentials are arbitrary, the complexity of even approximate minimization algorithms such as TRW-S grows quadratically both in the number of nodes and in the number of states a node can take.
