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

Claim 8:
9. A device, comprising
a memory storing program instructions; and
one or more processors, wherein the program instructions, when executed by the one or more processors, cause the one or more processors to:
generate 2D patch images for three-dimensional (3D) visual volumetric content;
scale one or more of the 2D patch images in 2D space, without requiring a corresponding 3D bounding box for the 2D patch image to be scaled by a same scaling factor in a same coordinate direction;
pack the scaled one or more 2D patch images into one or more two-dimensional (2D) image frames;
generate auxiliary information indicating:
respective 2D bounding boxes in the 2D image frames for the 2D patch images that have been scaled;
respective locations or characteristics of 3D bounding boxes in a 3D reconstructed version of the 3D visual volumetric content at which patches corresponding to the 2D patch images are to be located; and
an indication of the one or more scaling factors that have been applied in the 2D space; and

encode the one or more 2D image frames and the auxiliary information to generate a compressed version of the 3D visual volumetric content.
