However, (slower) fallback alternatives are used if these toolboxes are not found in most cases. The only function that requires image processing toolbox is the anisotropic diffusion MRP prior when using either implementation 1 or 4. Due to this, it does not work on Octave. A warning is produced if AD-MRP prior is used without the toolbox.</span></div><h3  class
