... exist outside the discrete series setting. In 1992, Mallat and Zhong [92] constructed a transform related to the original continuous wavelet transform, called the dyadic wavelet transform. Starting ... systematic construction of wavelet transforms. The book departs from a few basic realizations: Any wavelet transform V η is a unitary equivalence between π and a subrepresentation of λ G ,theleft regular ... some suitable subspace of L 2 (G). Indeed, in the case of the original wavelets arising from the ax + b-group, the focus of interest is on the action of that group on the real line by affine transformations,...
