Official rules

Sponsor

These Official Rules (“Rules”) govern the operation of the CVPR 2025 Photorealistic Avatar Challenge (see overview) Event Contest (“Contest”). Microsoft Corporation, One Microsoft Way, Redmond, WA, 98052, USA, is the Contest sponsor (“Sponsor”).

Definitions

In these Rules, “Microsoft”, “we”, “our”, and “us”, refer to Sponsor and “you” and “yourself” refers to a Contest participant, or the parent/legal guardian of any Contest entrant who has not reached the age of majority to contractually obligate themselves in their legal place of residence. “Event” refers to the CVPR 2025 Photorealistic Avatar Challenge (the “Event”). By entering you (your parent/legal guardian if you are not the age of majority in your legal place of residence) agree to be bound by these Rules.

Entry period

The Contest will operate from Jan 15, 2025 to April 7, 2025 (“Entry Period”). The Entry Period is divided into several periods as described in section How to Enter.

Eligibility

Open to any registered Event attendee 18 years of age or older. If you are 18 years of age or older but have not reached the age of majority in your legal place of residence, then you must have consent of a parent/legal guardian. Employees and directors of Microsoft Corporation and its subsidiaries, affiliates, advertising agencies, and Contest Parties are not eligible, nor are persons involved in the execution or administration of this promotion, or the family members of each above (parents, children, siblings, spouse/domestic partners, or individuals residing in the same household). Void in Cuba, Iran, North Korea, Sudan, Syria, Region of Crimea, and where prohibited. For business/tradeshow events: If you are attending the Event in your capacity as an employee, it is your sole responsibility to comply with your employer’s gift policies. Microsoft will not be party to any disputes or actions related to this matter.

How to enter

The Contest Objective is to promote collaborative research in photorealistic avatars aimed to maximize the subjective (perceptual) quality of avatars. Winners will be determined based on the subjective quality of the avatars using an online test framework described here (opens in new tab). Only models described in accepted CVPR Photorealistic Avatar Challenge papers will be eligible for winning the Contest. You may participate as an individual or a team. If forming a team, you must designate a “Team Captain” who will submit all entry materials on behalf of the team. Once you register as part of a Team, you cannot change Teams or alter your current team (either by adding or removing members) after the submission of your Entry. Limit one Entry per person and per team. You may not compete on multiple teams and you may not enter individually and on a team. We are not responsible for Entries that we do not receive for any reason, or for Entries that we receive but are not decipherable or not functional for any reason. Each Team is solely responsible for its own cooperation and teamwork. In no event will Microsoft officiate in any dispute regarding the conduct or cooperation of any Team or its members. The Contest will operate as follows: Registration / Development Period: January 15, 2025 to April 17, 2025. To register, please send an email to avatar_challenge@microsoft.com stating that you are interested to participate in the challenge. Please include the following details in your email:

  • Names of the participants and name of the team captain
  • Institution/Company
  • Email
  • Tentative title of the paper

Then, i. develop an avatar model that best meets the Contest Objective and ii. submit a CVPR 2025 Photorealistic Avatar Challenge paper via Microsoft Conference Management Toolkit (opens in new tab) (opens in new tab) which reports the computational complexity of the model in terms of the number of parameters. For the real-time track also include the time it takes to capture, process, and render a frame on a NVIDIA 4090 or equivalent GPU. To develop your model, use any available dataset for training data. The final evaluation will be conducted on a blind test set that is similar to the open sourced test set. On February 21, 2025 the blind test dataset will be made available. You will have until 11:59 PM PT on February 28, 2025 to test your model against this dataset and create a set of enhanced clips to submit for judging (your “Entry”). The rules of the challenge are as follows:

  • For real-time track, the frame processing must take less than the 33 ms on a NVIDIA 4090 or equivalent GPU. In addition, no future video frames can be used during processing for both encoding and decoding. The time constraint is for encoding + decoding (i.e., end-to-end time). For example, if capture+encoding takes 16ms and decoding (rendering) takes 16ms then the end-to-end time is 32ms which meets the real-time requirements.
  • For non-real-time tracks, there are no constraints on computation time, but no future video frames can be used during processing (for both encoding and decoding).
  • Winners will be picked based on the subjective MOS evaluated on the blind test set using the test framework described here (opens in new tab).
  • The blind test set will be made available to the participants on February 21, 2025. Participants must send the results achieved by their developed models to the organizers. We will use the submitted clips to conduct subjective evaluation and pick the winners based on the results. Participants are forbidden from using the blind test set to retrain or tune their models. Failing to adhere to these rules will lead to disqualification from the challenge.
  • Participants should report the computational complexity of their model in terms of the number of parameters and the time it takes to infer a frame on a NVIDIA 4090 or equivalent GPU.
  • Submitted papers will undergo the standard peer-review process of CVPR 2025. The paper needs to be accepted to the workshop for the participants to be eligible for the challenge.
    • New: Papers are optional for teams that already have a CVPR 2025 paper describing their avatar

CVPR 2025 Photorealistic Avatar Challange Paper Submission and Judging Period: March 15, 2025 11:59 PM PT to April 1, 2025.
