Claim 0:
1. A method for point cloud coding, comprising:
receiving, by a processor, a bitstream carrying compressed data for a point cloud;
determining, by the processor, that a current node in an octree structure is eligible for an isolated mode, the octree structure corresponding to three dimensional (3D) partitions of a space of the point cloud;
determining that a parent node of the current node only has a single child node that is the current node; and
inferring, by the processor, that a single isolated point flag for the current node has a false value in response to the current node being the single child node of the parent node, the single isolated point flag with the false value not being coded in the bitstream and the single isolated point flag with the false value indicating that the current node is not coded with a single isolated point.
