SCD4VPR: Multi-modal Scene Change Detection for Long-term Visual Place Recognition Database Update
Diwei Sheng, Vijayraj Gohil, Satyam Gaba +5
Long-term autonomy in mobile robotics requires maps that remain accurate as environments change over time. Visual Place Recognition (VPR), a core localization capability, degrades…
Can Foundation Models Reliably Identify Spatial Hazards? A Case Study on Curb Segmentation
Diwei Sheng, Giles Hamilton-Fletcher, Mahya Beheshti +2
Curbs serve as vital borders that delineate safe pedestrian zones from potential vehicular traffic hazards. Curbs also represent a primary spatial hazard during dynamic navigation…
NYC-Indoor-VPR: A Long-Term Indoor Visual Place Recognition Dataset with Semi-Automatic Annotation
Diwei Sheng, Anbang Yang, John-Ross Rizzo +1
Visual Place Recognition (VPR) in indoor environments is beneficial to humans and robots for better localization and navigation. It is challenging due to appearance changes at vari…
Distillation Improves Visual Place Recognition for Low Quality Images
Anbang Yang, Ge Jin, Junjie Huang +3
Real-time visual localization often utilizes online computing, for which query images or videos are transmitted to remote servers for visual place recognition (VPR). However, limit…
