Diagram of patch set construction. The top branch is the artifact-correction branch and the bottom branch is the artifact-free branch. Note that the whole ADN model contains four branches, and here only two branches are shown for illustrating patch construction as the artifact-affected images in the other branches are not constrained to have an LDM. Please refer to [17] for details of the whole ADN model.
