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.

Method and apparatus for encoding and decoding volumetric video data

Video encoding may comprise obtaining a volumetric content containing visual information of three-dimensional objects; generating at least one patch by projecting the visual information of three-dimensional objects of the volumetric content to at least one projection plane. Video decoding may comprise obtaining neighboring pixels of a location on the 2D image based on said geometry information; determining a difference of values of the neighboring pixels on the 2D image; comparing the difference with a value range to determine a number of 3D points to be interpolated; projecting back the 2D image to create the volumetric content; wherein the projection comprises interpolating the number of 3D points on the basis of the values of the neighboring pixels.
