MODEL-BASED PREDICTION FOR GEOMETRY POINT CLOUD COMPRESSION

Abstract:

Techniques are disclosed for coding point cloud data using a scene model. An example device for coding point cloud data includes a memory configured to store the point cloud data and one or more processors implemented in circuitry and communicatively coupled to the memory. The one or more processors are configured to determine or obtain a scene model corresponding with a first frame of the point cloud data, wherein the scene model represents objects within a scene, the objects corresponding with at least a portion of the first frame of the point cloud data. The one or more processors are also configured to code a current frame of the point cloud data based on the scene model.
