Navigating unfamiliar outdoor environments is one of the most demanding everyday tasks for people with visual impairments (PVI). However, existing navigation systems cannot simultaneously satisfy the needs of informative perception and precise localization during navigation. This paper explores the core navigation dema...

Vision-based document retrieval has improved rapidly, but current evaluation settings still emphasize short documents and single relevant pages. This leaves an important gap between leaderboard performance and realistic long-document retrieval, where the evidence needed to answer a query may span multiple pages or even...

SeqLoc is proposed, an online test-time sequence aggregation mechanism that recursively maintains a log-belief volume with three key components that outperforms single-frame localization by a large margin, improving both position and orientation recall by over 50%.
