AHG9: [GSC-related] Avatar Generation Information SEI message
Abstract
This contribution proposes an avatar generation information (AGI) SEI message to support the animation-based 3DGS avatar coding framework introduced in JVET-AQ0142. The proposed SEI message conveys the avatar attributes required to generate target avatar frames from a base 3DGS avatar. By signaling these avatar attributes together with the base 3DGS avatar, the decoder can derive target 3DGS avatars via human-template-based deformation, thereby enabling efficient avatar coding.

For information – no need for presentation according to proponents, further study in wider context across WGs, no action at this moment
