1. A method for decoding an image based on a base layer and enhancement information, said method comprising:
decoding said base layer to obtain at least one base component;
oversampling the at least one base component to obtain at least one oversampled component;
decoding the enhancement information using at least one artificial neural network portion to obtain enhancement values; and
reconstructing the image based on the at least one oversampled component and the decoded enhancement values.
