Entropy coding-based feature encoding/decoding method and device, recording medium having bitstream stored therein, and method for transmitting bitstream

Abstract

Herein provided are a feature encoding/decoding method, a recording medium storing a bitstream generated by the feature encoding method and a method of transmitting the bitstream. The feature decoding method may comprise obtaining channel information of a current coding unit, determining a context model for the current coding unit based on the channel information; and decoding the current coding unit based on the context model. The channel information may comprise channel grouping information of a feature map including the current coding unit, and the context model is determined based on the channel grouping information.
