A Rational-dilation Wavelet Transform with Signal Dependent Dilation Factor
This paper presents a fast and effective method for the selection of the
least number of scales able to represent significant information of a signal.
To this aim, atoms interference in the time-scale wavelet domain is used
to represent distinct configurations of transform coefficients; the goal is
to find those scales where transform coefficients change their configura-
tion. The selected set of scales cannot provide a dyadic partition of the
frequency domain. The rational dilation wavelet transform is a
