Understanding the Limitations of CNN-based Absolute Camera Pose Regression

1 code implementation CVPR 2019 Torsten Sattler, Qunjie Zhou, Marc Pollefeys, Laura Leal-Taixe

We furthermore use our model to show that pose regression is more closely related to pose approximation via image retrieval than to accurate pose estimation via 3D structure.

Lifting Layers: Analysis and Applications

1 code implementation ECCV 2018 Peter Ochs, Tim Meinhardt, Laura Leal-Taixe, Michael Moeller

A lifting layer increases the dimensionality of the input, naturally yields a linear spline when combined with a fully connected layer, and therefore closes the gap between low and high dimensional approximation problems.
