Image Matching Challenge 2020
Local features have played a key role in a wide range of computer vision applications throughout the past 20 years. Despite the drastic advancements in many fields after the deep learning revolution, end-to-end solutions for 3D reconstruction under challenging conditions remain elusive, and solutions based on traditional, hand-crafted methods such as SIFT (1999) and RANSAC (1981) may outperform the state of the art in machine learning.
Historically, local features have been evaluated on small datasets using proxy metrics, such as patch retrieval accuracy for descriptors. This may not necessarily translate to downstream applications, misrepresenting their actual performance and hindering the development of new techniques. There is a clear need for large-scale, challenging benchmarks to both train and evaluate new strategies for image matching. Towards this end, we held in 2019 an open challenge in image matching across wide baselines. In contrast to existing benchmarks, we only consider integrated solutions and our primary metric measures the accuracy of the reconstructed poses — the final goal.
We are pleased to introduce a second, much improved edition of this challenge. It is co-located with the CVPR 2020 workshop on Image Matching: Local Features and Beyond. Winners and selected participants will be invited to give talks at the conference, as last year. Prizes are available, thanks to our sponsors.
- March 18, 2020: Instructions to set up a scalable cluster to run the benchmark on Google Cloud.
- March 18, 2020: We have processed the first 8 challenge submissions (in the leaderboards). CVPR is still on track, despite the pandemic. We will hold the workshop if CVPR remains on. We plan to hold the challenge whether CVPR is held or not.
- March 3, 2020: Published benchmark paper on arxiv.
- February 10, 2020: Introducing the 2020 challenge.
- Challenge submission deadline: May 7, 2020
- Deadline for short descriptions on submissions: May 15, 2020
- Workshop date (CVPR'20): June 19, 2020 (morning)
We are improving the challenge in several ways, so conditions and dates may still change: stay tuned for updates.
