Abstract
A method, computer program, and computer system is provided for decoding point cloud data. Data corresponding to a point cloud is received. A number of contexts associated with the received data is reduced based on occupancy data corresponding to one or more parent nodes and one or more child nodes within the received data. The data corresponding to the point cloud is decoded based on the reduced number of contexts.
Claims20
A method of decoding point cloud data, executable by a processor, comprising:
- receiving data corresponding to a point cloud;
- reducing a number of contexts associated with the received data based on (i) occupancy data corresponding to one or more parent nodes of the current node and one or more child nodes of the current node within the received data, and (ii) a positional relationship of the one or more parent nodes with respect to the current node;
- and
- decoding the data corresponding to the point cloud based on the reduced number of contexts.
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 (i) occupancy data corresponding to one or more parent nodes of a current node and one or more child nodes of the current node within the received data, and (ii) a positional relationship of the one or more parent nodes with respect to the current node;
- and
- decoding code configured to cause the one or more computer processors to decode the data corresponding to the point cloud based on the reduced number of contexts.
A non-transitory computer readable medium having stored thereon a computer program for decoding point cloud data, the computer program configured to cause one or more computer processors to:
- receive data corresponding to a point cloud;
- reduce a number of contexts associated with the received data based on (i) occupancy data corresponding to one or more parent nodes of a current node and one or more child nodes of the current node within the received data, and (ii) a positional relationship of the one or more parent nodes with respect to the current node;
- and
- decode the data corresponding to the point cloud based on the reduced number of contexts.
