Abstract
Methods, systems, and bitstream syntax are described for a file container that supports the storage and transmission of multi-plane images. Examples are provided for coding texture and opacity information using HEVC or VVC coding and the HEIF container. Examples of carrying coded MPI images according to V3C and an example HEIF-based player are also presented.
Claims12
A method to store a multi-plane image (MPI) scene according to a High Efficiency Image File (HEIF) file container, the method comprising:
- generating an MPI image comprising two or more image layers, wherein each image layer comprises texture information and opacity information;
- packing the texture information layers to generate a 2D texture image;
- packing the opacity information layers to generate a 2D opacity image;
- packing the 2D texture image and the 2D opacity image to generate a packed image according to an image packing format;
- coding the packed image to generate a coded MPI image;
- generating MPI metadata for the coded MPI image;
- and
- combining the coded MPI image and the MPI metadata according to syntax semantics of the HEIF file container to generate a file-representation of the MPI image, wherein a coded media representation of the coded MPI image and the MPI metadata conforms to a visual volumetric video-based coding (V3C) specification.
