Abstract
Analyses based on Symmetric Daubechies Wavelets (SDW) lead to complex-
valued multiresolution representations of real signals. After a recall
of the construction of the SDW, we present some specific properties o
f these new types of Daubechies wavelets. We then discuss two applicat
ions in image processing: enhancement and restoration. In both cases,
the efficiency of this multiscale representation relies on the informa
tion encoded in the phase of the complex wavelet coefficients.
