Projects:RegistrationImprovement:RecursiveScheme

Both multi-resolution and the sequence of calls with increasing DOF could be implemented as a single recursive scheme. The caller provides an array of DOF and a matching array of resolution levels, which is processed by recursive calls with the first/last element taken from the list.

• A simulation Matlab program and example is here: Media:DOFHierarchy.m
• Example call: the 256 symbolizes the image data size, [6,9,12] is the sequence of DOF, NoInit is the initial transform (if avail), and [4,3,2] are the multi-resolution levels for each of the DOF runs, respectively.

 a = DOFHierarchy(256, [6,9,12],'NoInit',[4,3,2],0)
