METHOD AND APPARATUS FOR GEOMETRY SMOOTHING BY LOCAL GEOMETRY PROJECTION

摘要

Methods and apparatuses of decoding a video stream encoded using video point cloud coding include obtaining a geometry-reconstructed point cloud; dividing the geometry-reconstructed point cloud into a plurality of cells, wherein a cell of the plurality of cells includes a first plurality of points; determining a plane representing the first plurality of points; generating a second plurality of points by projecting the first plurality of points onto the plane; obtaining a smoothed geometry-reconstructed point cloud based on the second plurality of points; and reconstructing a dynamic point cloud using the smoothed geometry-reconstructed point cloud.
