Recent years have shown significant advances in immersive media experiences. Three-dimensional representation formats allow for new forms of entertainment and communication. In this context, point cloud data has emerged as a promising enabler for such experiences. Because efficient enough point cloud compression technologies are still to be found, the Moving Picture Expert Group (MPEG) has just issued a Call for Proposals (CfP) on point cloud compression technologies. This letter will present the MPEG CfP evaluation procedure and try to anticipate some of the many challenges to be faced when assessing point cloud compression performance.
