Abstract
The present principles generally relate to encoding and decoding of a point cloud representing the geometry of a point cloud representing a 3D object. According to the invention, prediction is used in the encoding process of the splitting information of the local octree-based structure and/or in the 10 encoding process of the occupancy information of the leaf cubes of the local octree-based structure. A predictor of the local octree-based structure is used for determining the context of the context-dependent entropy encoding in order to reduce the number of bits needed for the octree encoding.
