Abstract
One or more methods, apparatuses, computer-readable storage mediums, and systems for entropy coding vertex information of an edge in a voxelized space of a point cloud are disclosed. Symbols of a neighborhood configuration of a current edge may be determined based on one or more already coded edges. The already coded edges may be selected from a spatial topology of edges or its subset. A lookup table may be used to retrieve an index for a given occupancy configuration for a neighborhood of a current edge. The index may indicate an appropriate context or probability model. Based on the coding of the current edge, the lookup table may be updated.
