MURAUER: Mapping Unlabeled Real Data for Label AUstERity

1 code implementation23 Nov 2018 Georg Poier, Michael Opitz, David Schinagl, Horst Bischof

In this work, we remove this requirement by learning to map from the features of real data to the features of synthetic data mainly using a large amount of synthetic and unlabeled real data.

Deep 2.5D Vehicle Classification with Sparse SfM Depth Prior for Automated Toll Systems

no code implementations9 May 2018 Georg Waltner, Michael Maurer, Thomas Holzmann, Patrick Ruprecht, Michael Opitz, Horst Possegger, Friedrich Fraundorfer, Horst Bischof

Furthermore due to the design of the network, at test time only the 2D camera images are required for classification which enables the usage in portable computer vision systems.

Deep Metric Learning with BIER: Boosting Independent Embeddings Robustly

1 code implementation15 Jan 2018 Michael Opitz, Georg Waltner, Horst Possegger, Horst Bischof

To this end, we divide the last embedding layer of a deep network into an embedding ensemble and formulate training this ensemble as an online gradient boosting problem.
