Image Processing with Complex Daubechies Wavelets

  • Jean-Marc Lina
Article

Abstract

Analyses based on Symmetric Daubechies Wavelets (SDW) lead tocomplex-valued multiresolution representations of real signals.After a recall of the construction of the SDW, we present somespecific properties of these new types of Daubechies wavelets. Wethen discuss two applications in image processing: enhancement andrestoration. In both cases, the efficiency of this multiscalerepresentation relies on the information encoded in the phase of thecomplex wavelet coefficients.
