Quaternion wavelets for moving volume representation

As a pure academic exercise, Mitrea (1994) published a paper about Clifford wavelets. This is the more exhaustive approach to the subject, years before I published a paper completely unrelated about quaternion wavelets from a different point of view. I try to develop the idea of Mitrea a little more in terms of a “static” use of quaternion wavelets and also some of my own ideas related to its “dynamic” use
