AdaptVPR: Route-Aware Hard Positive Generation for Robust Visual Place Recognition

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.

Weather-Conditioned Depth Anything

Weather-Conditioned Depth Anything (DA‑W) is a new framework that enhances monocular depth estimation models, like the Depth Anything series, to perform robustly under adverse weather conditions such as fog, rain, snow, and low‑light. It achieves this by disentangling style from content: a Style Filter extracts weather‑specific embeddings from a curated mix of real and synthetic degradation data, which are then injected into the backbone via a lightweight, zero‑initialized adapter. The adapter is trained with pseudo‑label distillation and alignment, enabling a single unified model to adapt to diverse weather scenarios while preserving its generalization on clean data, and it achieves state‑of‑the‑art performance with an average 3.7% improvement in AbsRel on weather benchmarks.
