Abstract
An image decoding method includes: acquiring a neural-network post-filter characteristics (NNPFC) SEI message and a neural-network post-filter activation (NNPFA) SEI message; based on the NNPFC SEI message, determining at least one neural network which may be used as a neural-network post-processing filter; and based on the NNPFA SEI message, determining whether to activate a target neural-network post-processing filter that may be applied to the current picture. The NNPFA SEI message includes target identification information and target basic flag information of the target neural-network post-processing filter, the target neural-network post-processing filter is determined based on the target identification information and the target basic flag information, and based on that the target basic flag information does not indicate the target neural-network post-processing filter is a basic neural-network post-processing filter, at least one NNPFC SEI message is present before the NNPFA SEI in decoding order.
