Monocular Depth Estimation Challenge

These are the official rules (terms and conditions) that guvern how the Mobile 2022 challenge on Monocular Depth Estimation will operate. This challenge will be simply reffered to as the "challenge" or the "contest" throughout the remaining part of these rules and may be named as "MAI" or "Depth" benchmark, challenge, or contest, elsewhere (our webpage, our documentation, other publications).

In these rules, "we", "our", and "us" refer to the organizers (Andrey Ignatov (andrey [at] vision.ee.ethz.ch), Grigory Malivenko (nerox8664 [at] gmail.com), Samarth Shukla (Samarth.Shukla [at] vision.ee.ethz.ch), David Plowman (david.plowman [at] raspberrypi.com, and Radu Timofte (Radu.Timofte [at] vision.ee.ethz.ch)) of MAI challenge and "you" and "yourself" refer to an eligible contest participant.

Note that these official rules can change during the contest until the start of the final phase. If at any point during the contest the registered participant considers that can not anymore meet the eligibility criteria or does not agree with the changes in the official terms and conditions then it is the responsability of the participant to send an email to the organizers such that to be removed from all the records. Once the contest is over no change is possible in the status of the registered participants and their entries.

1. Contest description

This is a skill-based contest and chance plays no part in the determination of the winner (s).

The goal of the contest is to learn a mapper from an input image to an output depth image and the challenge is called Monocular Depth Estimation.

Focus of the contest: it will be made available a new dataset adapted for the specific needs of the challenge. The images have a large diversity of contents. We will refer to this dataset, its partition, and related materials as Depth Estimation Dataset. The dataset is divided into training, validation and testing data. We focus on quality of the results, the aim is to achieve depth images with the best fidelity to the reference ground truth depth image. The participants will not have access to the ground truth from the test data. The ranking of the participants is according to the performance of their methods on the test data and on the mobile platform. The participants will provide descriptions of their methods, details on (run)time complexity, platform and (extra) data used for modeling. The winners will be determined according to their entries, the reproducibility of the results and uploaded codes or executables, and the above mentioned criteria as judged by the organizers.

2. Tentative contest schedule

The registered participants will be notified by email if any changes are made to the schedule. The schedule is available on the Mobile AI workshop web page and on the Overview of the Codalab competition.

NOTE: industry and research labs are allowed to submit entries and to compete in both validation phase and final test phase. However, in order to get officially ranked on the final test leaderboard and to be eligible for awards the reproducibility of the results is a must and, therefore, the participants need to make available and submit their codes or executables. All the top entries will be checked for reproducibility and marked accordingly.

We will have 3 categories of entries in the final test ranking:
1) checked with publicly released codes 
2) checked with publicly released executable
3) unchecked (with or without released codes or executables)

4. Entry

In order to be eligible for judging, an entry must meet all the following requirements:

Entry contents: the participants are required to submit image results and code or executables. To be eligible for prizes, the top ranking participants should publicly release their code or executables under a license of their choice, taken among popular OSI-approved licenses (http://opensource.org/licenses) and make their code or executables online accessible for a period of not less than one year following the end of the challenge (applies only for top three ranked participants of the competition). To enter the final ranking the participants will need to fill out a survey (fact sheet) briefly describing their method. All the participants are also invited (not mandatory) to submit a paper for peer-reviewing and publication at the MAI Workshop and Challenges (to be held online on June, 2021). To be eligible for prizes, the participants score must improve the baseline performance provided by the challenge organizers.

If you are preparing multiple submissions, please contact the organizers in advance for clarification.

The terms and conditions are inspired by and use verbatim text from the `Terms and conditions' of ChaLearn Looking at People Challenges and of the NTIRE 2017, 2018, 2019, 2020, 2021 and 2022 challenges and of the AIM 2019, 2020 and 2021 challenges .
