Sequential encoding and decoding of volumetric video

Abstract

The invention relates to methods, apparatuses, systems and computer program products for coding volumetric video. A first texture picture coded, said first texture picture comprising a first projection of first volumetric texture data of a first source volume of a scene model and a second projection of second volumetric texture data of said first source volume of said scene model, said first projection being from said first source volume to a first projection surface, and said second projection being from said first source volume to a second projection surface, said second volumetric texture data having been obtained by removing at least a part of said first volumetric texture data that has been successfully projected in said first projection. A a first geometry picture is coded, said geometry picture representing a mapping of said first projection surface to said first source volume and a mapping of said second projection surface to said first source volume. Projection geometry information of said first and second projections is coded, said projection geometry information comprising information of position of said first and second projection surfaces in said scene model.
