Wavelets are a common tool for the analysis of signals in one or two
dimensions. Extending those ndings to be used in a three-dimensional
setting has proven more dicult. This report is concerned with a recent
promising approach to wavelet analysis in 3 dimensions on genus-0
objects, the so-called spherical wavelets. Using examples from the eld
of medical imaging, the concepts underlying their construction are
introduced and their usefullness for a variety of applications is
demonstrated. Further, an overview of publicly available toolboxes is
given and an evaluation comparing the capabilities of spherical
wavelets to dierent shape modelling approaches is performed.
