Abstract
At least a method and an apparatus are presented for efficiently encoding or decoding video. For example, a 2-D patch of the point cloud is obtained by projecting 3-D points of the point cloud onto a projection plane, the patch having a plurality of pixels. The patch is divided into a plurality of smaller blocks. The number of pixels is determined within each of the plurality of smaller blocks. An updated occupancy map is obtained based on the determined number of pixels within each of the plurality of smaller blocks. A reconstructed point cloud is obtained based on the updated occupancy map, wherein the reconstructed point cloud is a less dense representation of the point cloud.
