AdaptVPR introduces a route-aware generative augmentation framework that creates hard positive examples for Visual Place Recognition (VPR) training. It uses a vision‑language model to assess scene editability, a rule‑based scheduler to select generation routes, and a VPR‑oriented verification scheme to ensure geometric consistency and appearance diversity. The resulting AdaptCities dataset contains 160K verified synthetic hard positives, leading to consistent performance gains across VPR baselines, including up to 9.2% improvement in R@1 under challenging domain shifts.

Image segmentation remains challenging due to occlusions, poor lighting, and irregular structures. Although transformer-based methods achieve high accuracy, they rely heavily on long-range spatial fea...
SenseFuse introduces a label‑free fusion approach that balances 2D image and 3D shape encoders for open‑vocabulary 3D instance segmentation. By selecting a scene‑level fusion weight through an adaptive, sensitivity‑based mechanism, it improves mask labeling accuracy across multiple datasets, recovering up to 93% of the potential gain from an oracle weight. The method demonstrates that image and shape encoders have complementary failure patterns, leading to higher instance AP in most evaluated settings.
