We show how for n = 2,3(mod 4) continuous Clifford (geometric) algebra (GA)
Cl_n-valued admissible wavelets
can be constructed using the similitude group SIM(n).
We strictly aim for real geometric interpretation, and replace the
imaginary unit i element of C therefore with a GA blade squaring to
-1. Consequences due to non-commutativity arise. We express
the admissibility condition in terms of a Cl_n Clifford Fourier
Transform and then derive a set of important properties such as
dilation, translation and rotation covariance, a reproducing kernel,
and show how to invert the Clifford wavelet transform. As
an example, we introduce Clifford Gabor wavelets. We further invent a
generalized Clifford wavelet uncertainty principle.
