TCL: Tightly Coupled Learning Strategy for Weakly Supervised Hierarchical Place Recognition
RA-L 2022
Visual place recognition (VPR) is a key issue for robotics and autonomous systems. For the trade-off between time and performance, most of methods use the coarse-to-fine hierarchical architecture, which consists of retrieving top-N candidates using global features, and re-ranking top-N with local fe
