S2DNet: Learning Image Features for Accurate Sparse-to-Dense Matching

3 code implementations ECCV 2020 Hugo Germain, Guillaume Bourmaud, Vincent Lepetit

Establishing robust and accurate correspondences is a fundamental backbone to many computer vision algorithms.

Are Semi-Dense Detector-Free Methods Good at Matching Local Features?

no code implementations13 Feb 2024 Matthieu Vilain, Rémi Giraud, Hugo Germain, Guillaume Bourmaud

We then propose to limit the computation of the matching accuracy to textured regions, and show that in this case SAM often surpasses SDF methods.

Visual Correspondence Hallucination

no code implementations ICLR 2022 Hugo Germain, Vincent Lepetit, Guillaume Bourmaud

Given a pair of partially overlapping source and target images and a keypoint in the source image, the keypoint's correspondent in the target image can be either visible, occluded or outside the field of view.

Back to the Feature: Learning Robust Camera Localization from Pixels to Pose

2 code implementations CVPR 2021 Paul-Edouard Sarlin, Ajaykumar Unagar, Måns Larsson, Hugo Germain, Carl Toft, Viktor Larsson, Marc Pollefeys, Vincent Lepetit, Lars Hammarstrand, Fredrik Kahl, Torsten Sattler

In this paper, we go Back to the Feature: we argue that deep networks should focus on learning robust and invariant visual features, while the geometric estimation should be left to principled algorithms.

Neural Reprojection Error: Merging Feature Learning and Camera Pose Estimation

1 code implementation CVPR 2021 Hugo Germain, Vincent Lepetit, Guillaume Bourmaud

Absolute camera pose estimation is usually addressed by sequentially solving two distinct subproblems: First a feature matching problem that seeks to establish putative 2D-3D correspondences, and then a Perspective-n-Point problem that minimizes, with respect to the camera pose, the sum of so-called Reprojection Errors (RE).
