Paper Abstract

A new approach on the construction of wavelet-frames (affine frames) is presented. It uses a new concept of affine pseudo frames, and a generalized multiresolution structure (GMS). The freedom gained from using pseudo frames allows us to design filters of rapid decay. A fast numerical algorithm for the affine frame decomposition and reconstruction is also a natural consequence of the GMS structure. Examples on applications to data compression and noise suppression are presented. Results are encouraging.
