DisPlacing Objects: Improving Dynamic Vehicle Detection via Visual Place Recognition under Adverse Conditions

Stephen Hausler, Sourav Garg, Punarjay Chakravarty +3

Can knowing where you are assist in perceiving objects in your surroundings, especially under adverse weather and lighting conditions? In this work we investigate whether a prior m…

Locking On: Leveraging Dynamic Vehicle-Imposed Motion Constraints to Improve Visual Localization

Stephen Hausler, Sourav Garg, Punarjay Chakravarty +3

Most 6-DoF localization and SLAM systems use static landmarks but ignore dynamic objects because they cannot be usefully incorporated into a typical pipeline. Where dynamic objects…

Category-Level Pose Retrieval with Contrastive Features Learnt with Occlusion Augmentation

Georgios Kouros, Shubham Shrivastava, Cédric Picron +3

Pose estimation is usually tackled as either a bin classification or a regression problem. In both cases, the idea is to directly predict the pose of an object. This is a non-trivi…

Improving Worst Case Visual Localization Coverage via Place-specific Sub-selection in Multi-camera Systems

Stephen Hausler, Ming Xu, Sourav Garg +4

6-DoF visual localization systems utilize principled approaches rooted in 3D geometry to perform accurate camera pose estimation of images to a map. Current techniques use hierarch…
