Abstract
Methods, apparatus, systems and articles of manufacture for object-based volumetric video coding are disclosed. An example apparatus disclosed herein includes a point annotator to receive point cloud data associated with an object and annotate points of the point cloud data with an object identifier of the object. The disclosed example apparatus also includes a projector to project the point cloud data onto projection planes to produce texture images and geometry images. The disclosed example apparatus further includes a patch generator to generate a patch based on the object identifier, the patch including the texture images and the geometry images of the object, the patch associated with the object identifier of the object. The disclosed example apparatus also includes an atlas generator to generate an atlas to include in encoded video data, the atlas including the patch.
