Abstract
In one implementation, a method of encoding or decoding point cloud data is provided, comprising: obtaining upsampled attributes of a previous octree level of the point cloud data; predicting attributes of a current voxel group of a current octree level of the point cloud data, based on attributes of already encoded/decoded voxel groups in the current octree level and the upsampled attributes of the previous octree level; obtaining a probability distribution of the current voxel group, based on the predicted attributes of the current voxel group; and encoding the current voxel group into a bitstream or decoding the current voxel group from an input bitstream, based on the probability distribution of the current voxel group.
