Methods for encoding and decoding feature data, and decoder

Abstract

Embodiments of the disclosure provide a method for encoding feature data, a method for decoding feature data, and a decoder. The method for encoding feature data includes the following. Feature data of multiple channels corresponding to a picture to-be-processed is obtained. Feature data of a reference channel in the feature data of the multiple channels is determined. Sorted feature data of the multiple channels is obtained by sorting, starting from the feature data of the reference channel, the feature data of the multiple channels in a descending order of similarity among the feature data of the multiple channels. The sorted feature data of the multiple channels is spliced to obtain a target feature frame sequence. The target feature frame sequence is encoded to generate a bitstream.

Dependencies are inferred from the claim text.
