Assignee: APPLE INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 13:
14. A device, comprising:
a memory storing program instructions; and
one or more processors,
wherein the program instructions, when executed on or across the one or more processors, cause the one or more processors to:
receive a bit stream comprising encoded attribute information for three-dimensional (3D) visual content, wherein the encoded attribute information comprises attribute correction values for points of the 3D visual content; and
for respective ones of the points of the 3D visual content:
identify a set of neighboring points that neighbor the respective point;
determine a predicted attribute value for the respective point based, at least in part, on predicted or assigned attribute values for the neighboring points and respective distances between the respective point and respective ones of the neighboring points; and
apply a corresponding one of the attribute correction values to the predicted attribute value determined for the respective point to generate a reconstructed attribute value for the respective point; and

provide a reconstructed version of the 3D visual content comprising the reconstructed attribute values for the respective ones of the points.
