Video based point cloud compression-patch alignment and size determination in bounding box
A system comprises an encoder configured to compress attribute information and/or spatial for a point cloud and/or a decoder configured to decompress compressed attribute and/or spatial information for the point cloud. To compress the attribute and/or spatial information, the encoder is configured to convert a point cloud into an image based representation. Also, the decoder is configured to generate a decompressed point cloud based on an image based representation of a point cloud. The encoder generates an occupancy map and may adjust a size or placement of a patch in the occupancy map to reduce or eliminate redundant points caused by down-sampling and up-sampling of the occupancy map.
