Title:
METHOD AND APPARATUS OF ENCODING/DECODING SERIES OF DATA
Document Type and Number:
WIPO Patent Application WO/2023/103639
Kind Code:
A1
Abstract:
The encoding method obtains a reduced current neighborhood configuration by applying a dynamic reduction function (DRn) on a current neighborhood configuration of a set of candidate neighborhood configurations relative to a current data of the series of data. The image of the DRn is a set of reduced neighborhood configurations and each reduced neighborhood configuration is associated with a leaf node of a tree. The reduced current neighborhood configuration is obtained by progressing from a root node of the tree until a leaf node based on values of constitutive elements of the current neighborhood configuration. The method encodes current data by using an entropy coder of a set of entropy coders, said entropy coder being selected based on the reduced current neighborhood configuration, increments a number of use relative to the use of the reduced current neighboring information, and updates the DRn if said number of use exceeds a threshold.
