V3C-based Coding of Dynamic Meshes

ISO/IEC JTC1 SC29, also called MPEG, has been working on a compression standard for dynamic meshes since couple of year now and it has released a Call for Proposals (CfP) for Dynamic Mesh Coding in October 2021. One of the goals of the future standard is to utilize the Visual Volumetric Video-based Coding (V3C) framework, defined in ISO/IEC 23090-5, that is already used for dynamic point cloud compression and volumetric video. In this paper, the authors described their vision of how dynamic mesh compression could be achieved, which corresponds to their technical response to the CfP. The presented objective and subjective results will show that the proposed solution outperforms the anchor in terms of objective metrics and subjective perceived visual quality for low bit rate use cases.
