Abstract

An image encoding/decoding method, a bitstream transmission method, and a computer-readable recording medium on which a bitstream is stored are provided. The image decoding method, according to the present disclosure, is a method by which an image decoding device decodes an image, and comprises the steps of: acquiring, from a neural-network post-filter characteristics (NNPFC) supplemental enhancement information (SEI) message, first information indicating whether at least one output picture corresponding to at least one input picture is generated; and acquiring, from a neural-network post-filter activation (NNPFA) SEI message, second information indicating whether the generated output picture is output, wherein the value of the second information is determined on the basis of whether the objective of the neural-network post-filter (NNPF) is picture rate upsampling or whether the input picture is plural in number.
