Classification: CPC G | IPC G

Claim 7:
8. A computer system for decoding point cloud data, the computer system comprising:
one or more computer-readable non-transitory storage media configured to store computer program code; and
one or more computer processors configured to access said computer program code and operate as instructed by said computer program code, said computer program code including:
receiving code configured to cause the one or more computer processors to receive data corresponding to a point cloud;
reducing code configured to cause the one or more computer processors to reduce a number of contexts associated with the received data based on reducing a size of an context array corresponding to syntax elements for predictive tree-based coding of the point cloud, wherein the context array is a three-dimensional array that indicates a total number of contexts required to encode the syntax elements associated with the received data, wherein the reducing comprises reducing a size of at least one dimension of the context array from a first value to a second value less than the first value; and
first decoding code configured to cause the one or more computer processors to decode the received data corresponding to the point cloud based on the reduced number of contexts.
