You're not part of this competition. Yet...Join the competition!
The official prize phase of this competition is over, but it remains open for practice and learning.
Ground truth labels are available on the Data Download page for all 50K Phase 1 query images, as well as the 25K public subset from Phase 1 (you must be signed up for the competition). You'll also find an evaluation script there that you can use to compute your score now that new submissions are no longer being accepted.
The methods developed by the contestants are of high quality and set a new standard in research and for the industry in the field of image copy detection.
— Matthijs Douze, Facebook AI Research Scientist and Image Similarity Challenge author
Copy detection is a crucial component on all social media platforms today, used for such tasks as flagging misinformation and manipulative advertising, preventing uploads of graphic violence, and enforcing copyright protections. But when dealing with the billions of new images generated every day on sites like Facebook, manual content moderation just doesn't scale. We need algorithms to help automatically flag or remove bad content.
This competition allowed participants to test their skills in building a key part of that content moderating system, and in so doing contribute to making social media more trustworthy and safe for the people who use it. For more information, check out the competition paper from Facebook AI.
In this challenge, participants had access to 3 archives of competition images.
- 1 million reference images
- 50K query images, a subset of which were derived from the reference images
- 1 million training images, statistically similar to but distinct from the reference archive
The core task in the Matching Track was to determine for each query image whether it originated from one of the reference images and assign a confidence score indicating its similarity to the candidate reference image. The end goal was similar for the Descriptor Track, but in this case participants submitted the image embeddings for all query and reference images, with a similarity search and submission score computed automatically on the competition platform.
Between June and October 2021, 1,236 participants from 80 countries signed up to solve the problems posed by the two tracks. One goal of the competition sponsors at Facebook AI was to create an opportunity for participants to explore self-supervised learning (SSL) techniques, which turned out to be a key component across all of the winning solutions. Ultimately, the winning solutions vastly outperformed the competition baseline methods, achieving micro average precision scores of 0.8329 and 0.6354 on the Matching and Descriptor tracks, respectively.
All the prize-winning solutions from this competition have been released under an open source license, along with academic write-ups on arxiv. The dataset and ground truth labels from Phase 1 are also available for ongoing practice and learning.

Selection of winners
This Competition is a challenge of skill and the final results are determined by evaluating a combination of quantitative and qualitative factors, as more fully described on the Competition Website. The Competition results will be determined by leaderboard ranking, subject to verification by the Competition Entities, on the Phase II leaderboard based on an objective statistical evaluation metric published on the Competition Website, and compliance with these Competition Rules and any directions or requirements set forth on the Competition Website. Phase I leaderboard standings do not impact Competition outcome or the award of any Prizes. Participants' scores and ranks on the Competition Website at any given stage of the Competition will be based on the objective statistical evaluation metric described on the Competition Website, as determined by applying the predictions in the Submission to the ground truth of a validation dataset whose instances were a fixed set sampled from the Data. As more fully described on the Competition Website, the Competition will have quantitative winner(s) in each Track. Phase II leaderboard rankings posted on the Competition Website are not dispositive and all scores and winner determinations are subject to verification by Competition Entities.
The evaluation metric used for scoring and ranking Submissions will be displayed on the Competition Website.
Any prize awards are subject to verification of eligibility and compliance with these Competition Rules. All decisions of DrivenData, the Competition Sponsor and/or judges will be final and binding on all matters relating to this Competition. Competition Entities reserve the right to examine the Submission and any associated code, documentation or External Data for compliance with these Competition Rules.
