Title:
OCCUPANCY INFORMATION PREDICTION METHOD, ENCODER, DECODER, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/062743
Kind Code:
A1
Abstract:
Embodiments of the present application provide an occupancy information prediction method, an encoder, a decoder, and a storage medium. The occupancy information prediction method comprises: when an encoder encodes geometrical information on the basis of an octree, determining occupancy information corresponding to neighboring nodes of a node awaiting prediction, an encoding status of the neighboring nodes, the number of occupied child nodes of encoded neighboring nodes among the neighboring nodes, and a distance parameter between child nodes of the node awaiting prediction and the neighboring nodes; acquiring a preconfigured weight set according to the distance parameter and the number of occupied child nodes; determining occupancy weights corresponding to the child nodes according to the preconfigured weight set, the encoding status, and the occupancy information; performing prediction processing on the child nodes according to the occupancy weights and a preconfigured occupancy threshold set so as to acquire node types corresponding to the child nodes; and outputting predicted occupancy information of the node awaiting prediction on the basis of the node types.
