Abstract: A method, apparatus, and computer program product provide for compression of volumetric video in a manner that is more efficient and requires less metadata updates. A method can include converting a volumetric video scene into a canonical representation comprising a plurality of frames comprising a video atlas and corresponding metadata. Each frame can be divided into a plurality of tiles based on different tile characteristics, which can be used to analyze and characterize the different tiles for atlas packing purposes. Tiles can be clipped or merged or otherwise edited in the atlas. Tiles can be decomposed to metadata suitable for later rendering of the tile. Tiles having a similar enough color attribute or depth attribute during the entire group of photos can be rendered as a single instance, clipped entirely, and rendered based upon a reference tile and the stored metadata.

Abstract: A method, apparatus and computer program product provide for encoding and decoding volumetric video data. In relation to encoding, one or more patches into which a point cloud representative of volumetric video data has been decomposed are evaluated by identifying one or more areas within a respective patch in which a difference in depth values between corresponding pixels of at least two depth planes satisfy a predefined threshold. For an area within the respective patch that has been identified, a sub patch is generated representative of the depth values of one of the depth planes. The patches are mapped including the one or more patches and the sub patch to a grid and an image is generated based upon the patches mapped to the grid.
