Paper Abstract

We present some preliminary results of constructions of biorthogonal wavelets and associated filterbanks with optimality using a tool of pseudoframes for subspaces (PFFS). PFFS extends the theory of frames in that pseudoframe sequences need not reside within the subspace of interests. The flexibility so introduced proves favorably in the construction of biorthogonal wavelets. While past constructions pioneered by Cohen, Daubechies, and Feauveau can be reproduced precisely, results of additional optimalities are also obtained. Some preliminary examples are reported.
