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 comprises the steps of acquiring a neural-network post-filter (NNPF) supplemental enhancement information (SEI) message; determining, on the basis of at least one neural-network post-filter characteristics (NNPFC) SEI message included in the NNPF SEI message, at least one neural network that can be used as a post-processing filter, on the basis that the NNPF SEI message is applied to a current picture; and determining, on the basis of at least one neural-network post-filter activation (NNPFA) included in the NNPF SEI message, whether a target neural-network post-processing filter applicable to the current picture is activated, wherein the target neural-network post-processing filter is determined as a neural-network post-processing filter of the last NNPFC SEI message, from among NNPFC SEI messages, of a decoding order.
