UniPR-3D: Towards Universal Visual Place Recognition with Visual Geometry Grounded Transformer
Tianchen Deng, Xun Chen, Ziming Li +5
Visual Place Recognition (VPR) has been traditionally formulated as a single-image retrieval task. Using multiple views offers clear advantages, yet this setting remains relatively…
Rheos: Modelling Continuous Motion Dynamics in Hierarchical 3D Scene Graphs
Iacopo Catalano, Francesco Verdoja, Javier Civera +2
3D Scene Graphs (3DSGs) provide hierarchical, multi-resolution abstractions that encode the geometric and semantic structure of an environment, yet their treatment of dynamics rema…
MAG-VLAQ: Multi-modal Aerial-Ground Query Aggregation for Cross-View Place Recognition
Zhengyi Xu, Yuhang Ming, Zhihao Zhan +3
Multi-modal cross-view place recognition remains a fundamental challenge in computer vision and robotics due to the severe viewpoint, modality, and spatial-structure discrepancies…
Cross-Attentive Multiview Fusion of Vision-Language Embeddings
Tomas Berriel Martins, Martin R. Oswald, Javier Civera
Vision-language models have been key to the development of open-vocabulary 2D semantic segmentation. Lifting these models from 2D images to 3D scenes, however, remains a challengin…
Aion: Towards Hierarchical 4D Scene Graphs with Temporal Flow Dynamics
Iacopo Catalano, Eduardo Montijano, Javier Civera +2
Autonomous navigation in dynamic environments requires spatial representations that capture both semantic structure and temporal evolution. 3D Scene Graphs (3DSGs) provide hierarch…
DC-VLAQ: Query-Residual Aggregation for Robust Visual Place Recognition
Hanyu Zhu, Zhihao Zhan, Yuhang Ming +4
One of the central challenges in visual place recognition (VPR) is learning a robust global representation that remains discriminative under large viewpoint changes, illumination v…
