Patent number: 10869059Abstract: A system comprises an encoder configured to compress a point cloud comprising a plurality of points each point comprising spatial information for the point. The encoder is configured to sub-sample the points and determine subdivision locations for the subsampled points. Also, the encoder is configured to determine, for respective subdivision location, if a point is to be included, not included, or relocated relative to the subdivision location. The encoder encodes spatial information for the sub-sampled points and encodes subdivision location point inclusion/relocation information to generate a compressed point cloud. A decoder recreates an original or near replica of an original point cloud based on the spatial information and the subdivision location inclusion/relocation information included in the compressed point cloud.Type: GrantFiled: May 11, 2020Date of Patent: December 15, 2020Assignee: Apple Inc.Inventors: Khaled Mammou, Fabrice A. Robinet, Andrea Cremaschi, Alexandros Tourapis
