Paper Abstract
Probably the most important property of wavelets for signal processing is their multiscale derivative-like behavior
when applied to functions. In order to extend the class of problems that can profit of wavelet-based techniques, we
propose to build new families of wavelets that behave like an arbitrary scale-covariant operator. Our extension is
general and includes many known wavelet bases. At the same time, the method takes advantage a fast filterbank
decomposition-reconstruction algorithm. We give necessary conditions for the scale-covariant operator to admit
our wavelet construction, and we provide examples of new wavelets that can be obtained with our method.
