Title:
METHOD, APPARATUS, AND MEDIUM FOR POINT CLOUD CODING
Document Type and Number:
WIPO Patent Application WO/2024/083194
Kind Code:
A1
Abstract:
Embodiments of the present disclosure provide a solution for point cloud coding. A method for point cloud coding is proposed. The method comprises: determining, during a conversion between a current frame of a point cloud sequence and a bitstream of the point cloud sequence, a plurality of azimuthal angle metric values of a plurality of key points associated with a node of the current frame, the node representing a spatial partition of the current frame; determining a prediction of azimuthal angle metric value of the node; determining a context of entropy coding for a plane position of at least one axis associated with the node based on the plurality of azimuthal angle metric values and the prediction of azimuthal angle metric value; and performing the conversion based on the context of entropy coding.
