Hello organizers, I would like to clarify the workshop paper and registration requirements for teams participating in multiple tasks. If one team participates in multiple tasks, is it required to submit a separate workshop/methodology paper for each task, or can one paper cover all participated tasks? Also, if separate workshop papers are required for multiple tasks, but only one team member registers for and attends the workshop, would one registration fee be sufficient, or is a separate registration fee required for each accepted paper/task? In addition, we would like to ask about the final ranking metrics for each task. The current validation leaderboard appears to be ranked only by SSIM. Will the final test leaderboard also be ranked only by SSIM, or will it use the full set of metrics described on the challenge website, such as nRMSE, SSIM, LPIPS, Dice, and normalized volume consistency, with a composite ranking? We want to make sure we correctly understand the paper submission, registration, and final evaluation policies. Thank you.
