VDNA-PR: Using General Dataset Representations for Robust Sequential Visual Place Recognition

no code implementations14 Mar 2024 Benjamin Ramtoula, Daniele De Martini, Matthew Gadd, Paul Newman

Two parallel lines of work on VPR have shown, on one side, that general-purpose off-the-shelf feature representations can provide robustness to domain shifts, and, on the other, that fused information from sequences of images improves performance.
