The goal of the Grand Challenge is to advance algorithms that enhance real-world, dynamic (4D) color point clouds by producing accurate, temporally consistent, and visually faithful reconstructions from consumer-grade captures.
Participants from all over the world can participate in the challenge. The participants must be of
legal age to participate. The maximum team size is 5. Each Team is required to appoint a team
leader. This team leader will be the main contact point between the Organizers and the Team.
