Description of three different possibilities to implement a Lange prior: standard or local, smoothed, and patch-based. For each implementation, the value used for the voxel Inline graphic, the voxel Inline graphic, and the intensity difference between them is shown; as well as the level (voxel, patch, neighbors, and image) at which the intensity differences are sum in the potential function Inline graphic and in the energy function Inline graphic.
