Abstract

Disclosed herein are an image decoding/encoding method, a storage medium storing a bitstream and a method for transmitting a bitstream. According to an aspect of the present disclosure, an image decoding method include obtaining a NNPF SEI message, the NNPF SEI message including a NNPFC SEI message and a NNPFA SEI message, determining a neural-network that can be used as a post-processing filer based on the NNPFC SEI message, and determining whether to activate a target NNPF that can be applied to the current picture based on the NNPFA SEI message, wherein the target NNPF is used for post-processing filtering for the current picture and subsequent pictures of a current layer in output order until a picture in a current layer associated with an NNPFA SEI message with the same target NNPF ID information as a current SEI message is output that follows the current picture in the output order.
