Zusammenfassung:	This application provides a method and an apparatus for encoding and decoding a region enhancement layer. The method for encoding the region enhancement layer in this application includes: obtaining reconstructed pixels of a base layer of a target region; inputting the reconstructed pixels into a correction network to obtain correction information of the target region; inputting the correction information and original pixels of the target region into an encoding network to obtain a residual feature map of an enhancement layer of the target region; and encoding the residual feature map to obtain an enhancement layer bitstream of the target region. This application can improve encoding efficiency and encoding precision of the enhancement layer.
