DeDoDe v2: Analyzing and Improving the DeDoDe Keypoint Detector

1 code implementation13 Apr 2024 Johan Edstedt, Georg Bökman, Zhenjun Zhao

First, we find that DeDoDe keypoints tend to cluster together, which we fix by performing non-max suppression on the target distribution of the detector during training.

Steerers: A framework for rotation equivariant keypoint descriptors

1 code implementation4 Dec 2023 Georg Bökman, Johan Edstedt, Michael Felsberg, Fredrik Kahl

Image keypoint descriptions that are discriminative and matchable over large changes in viewpoint are vital for 3D reconstruction.

Leveraging Cutting Edge Deep Learning Based Image Matching for Reconstructing a Large Scene from Sparse Images

no code implementations2 Oct 2023 Georg Bökman, Johan Edstedt

We present the top ranked solution for the AISG-SLA Visual Localisation Challenge benchmark (IJCAI 2023), where the task is to estimate relative motion between images taken in sequence by a camera mounted on a car driving through an urban scene.

Leveraging the Power of Data Augmentation for Transformer-based Tracking

no code implementations15 Sep 2023 Jie Zhao, Johan Edstedt, Michael Felsberg, Dong Wang, Huchuan Lu

Due to long-distance correlation and powerful pretrained models, transformer-based methods have initiated a breakthrough in visual object tracking performance.

RoMa: Robust Dense Feature Matching

1 code implementation24 May 2023 Johan Edstedt, Qiyu Sun, Georg Bökman, Mårten Wadenbäck, Michael Felsberg

The aim is to learn a robust model, i. e., a model able to match under challenging real-world changes.

Camera Calibration without Camera Access -- A Robust Validation Technique for Extended PnP Methods

no code implementations14 Feb 2023 Emil Brissman, Per-Erik Forssén, Johan Edstedt

The first question is how to find the projection model that describes the camera, and the second is to detect incorrect models.

DKM: Dense Kernelized Feature Matching for Geometry Estimation

1 code implementation CVPR 2023 Johan Edstedt, Ioannis Athanasiadis, Mårten Wadenbäck, Michael Felsberg

This changes with our novel dense method, which outperforms both dense and sparse methods on geometry estimation.

Dense Gaussian Processes for Few-Shot Segmentation

1 code implementation7 Oct 2021 Joakim Johnander, Johan Edstedt, Michael Felsberg, Fahad Shahbaz Khan, Martin Danelljan

Given the support set, our dense GP learns the mapping from local deep image features to mask values, capable of capturing complex appearance distributions.

Deep Gaussian Processes for Few-Shot Segmentation

no code implementations30 Mar 2021 Joakim Johnander, Johan Edstedt, Martin Danelljan, Michael Felsberg, Fahad Shahbaz Khan

Through the expressivity of the GP, our approach is capable of modeling complex appearance distributions in the deep feature space.
