no code implementations • 29 Nov 2023 • Silvan Weder, Francis Engelmann, Johannes L. Schönberger, Akihito Seki, Marc Pollefeys, Martin R. Oswald

Using these main contributions, our method can enable scenarios with real-time constraints and can scale to arbitrary scene sizes by processing and updating the scene only in a local region defined by the new measurement.

SGM-Nets: Semi-Global Matching With Neural Networks

no code implementations • CVPR 2017 • Akihito Seki, Marc Pollefeys

Moreover, we propose a novel SGM parameterization, which deploys different penalties depending on either positive or negative disparity changes in order to represent the object structures more discriminatively.

Quad-networks: unsupervised learning to rank for interest point detection

In this paper, we ask a fundamental question: can we learn such detectors from scratch?
