    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 apparatus, and a computer-readable recording medium generated by the feature encoding method are provided. The feature decoding method according to the present disclosure may comprise the steps of: acquiring, from a bitstream, first feature information and filtering information regarding the first feature information; inversely transforming the first feature information; and deriving, on the basis of the filtering information, second feature information for the inversely transformed first feature information.

    Abstract: An image encoding/decoding method and apparatus are provided. An image decoding method may comprise obtaining, from a bitstream, a feature set extracted from an input image using an artificial neural network-based feature extraction method, first information on importance of each of a plurality of channels included in the feature set and second information on a quantization method of the feature set, decoding the feature set, the first information and the second information, and dequantizing the decoded feature set based on the decoded first information and the decoded second information. The second information may comprise the number of quantization bits of each of the plurality of channels, and the number of quantization bits may be determined based on the importance of each of the plurality of channels.
