Abstract: Provided are a feature encoding/decoding method and device, and a computer-readable recording medium generated by the feature encoding method. The feature decoding method according to the present disclosure may comprise the steps of: determining, on the basis of first information, whether quantization parameter (QP) information on feature channels is encoded in units of feature channels; acquiring the QP information from a bitstream on the basis that the QP information is encoded in units of feature channels; and setting QP values for the feature channels on the basis of the QP information.

Abstract: Provided are a feature encoding/decoding method and device, and a computer-readable recording medium generated by the feature encoding method. A feature decoding method, according to the present disclosure, is a feature decoding method performed by a feature decoding device and may comprise the steps of: dividing a current feature channel into feature blocks on the basis of information on division of the current feature channel; and reconstructing a current feature block on the basis of first transform information which is information on a transform of the current feature block from among the feature blocks.

Abstract: Provided are a feature encoding/decoding method and device, and a computer-readable recording medium generated by the feature encoding method. The feature decoding method according to the present disclosure is performed by a feature decoding device, and comprises the steps of: acquiring, from a bit-stream, parameter information related to a plurality of layers; and recovering feature information about the plurality of layers on the basis of the parameter information, wherein the parameter information can include information about the number of feature channels and/or information about a quantization parameter (QP).
