M. Duvaldestin et al., CONTINUOUS WAVELET DECOMPOSITIONS, MULTIRESOLUTION, AND CONTRAST ANALYSIS, SIAM journal on mathematical analysis, 24(3), 1993, pp. 739-755
A continuous version of multiresolution analysis is described, startin
g from usual continuous wavelet decompositions. Scale discretization l
eads to decompositions into functions of arbitrary bandwidth, satisfyi
ng QMF-like conditions. Finally, a nonlinear multiresolution scheme is
described, providing multiplicative reconstruction formulas.
