TRAIL: Trajectory-Aware Visual Place Recognition against Unordered Databases
Dominik A. Kloepfer, Patrick Wenzel
Modern Visual Place Recognition (VPR) methods excel on standard benchmarks yet remain brittle in feature-poor environments. By treating each query image in isolation, they discard…
SCENES: Subpixel Correspondence Estimation With Epipolar Supervision
Dominik A. Kloepfer, João F. Henriques, Dylan Campbell
Extracting point correspondences from two or more views of a scene is a fundamental computer vision problem with particular importance for relative camera pose estimation and struc…
LoCUS: Learning Multiscale 3D-consistent Features from Posed Images
Dominik A. Kloepfer, Dylan Campbell, João F. Henriques
An important challenge for autonomous agents such as robots is to maintain a spatially and temporally consistent model of the world. It must be maintained through occlusions, previ…
Delving Into Deep Walkers: A Convergence Analysis of Random-Walk-Based Vertex Embeddings
Dominik Kloepfer, Angelica I. Aviles-Rivero, Daniel Heydecker
Graph vertex embeddings based on random walks have become increasingly influential in recent years, showing good performance in several tasks as they efficiently transform a graph…
