A Theory of Pseudoframes for Subspaces with Applications
نویسندگان
چکیده
We de ne and characterize a frame-like stable decomposition for subspaces of a general separable Hilbert space. We call it pseudoframes for subspaces (PFFS). Properties of PFFS are discussed. A necessary and su cient characterization of PFFSs is provided. Analytical formulae for the construction of PFFSs are derived. Examples and applications of PFFSs are discussed.

Beurling Dimension of Gabor Pseudoframes for Affine Subspaces
Pseudoframes for subspaces have been recently introduced by S. Li and H. Ogawa as a tool to analyze lower dimensional data with arbitrary flexibility of both the analyzing and the dual sequence. In this paper we study Gabor pseudoframes for affine subspaces by focusing on geometrical properties of their associated sets of parameters. We first introduce a new notion of Beurling dimension for dis...
متن کاملPseudoframes for Subspaces with Applications
A notion of pseudoframes for subspaces (PFFS) is defined and characterized in a separable Hilbert space H. PFFS functions in a manner of a frame for a subspace X in H. Yet none of the pair of sequences {xn} and {x∗ n} is necessarily contained in X . This gives rise to attractive properties that center around the flexibility. A necessary and sufficient characterization of PFFSs is provided. Anal...
متن کاملParametric Optimization of Biorthogonal Wavelets and Filterbanks via Pseudoframes for Subspaces
We present constructions of biorthogonal wavelets and associated filter banks with optimality using pseudoframes for subspaces (PFFS). PFFS extends the theory of frames in that pseudoframe sequences need not reside within the subspace of interest. In particular, when PFFS is applied to biorthogonal wavelets the underlying flexibility presents opportunities to incorporate optimality, regularity ...
متن کاملBiorthogonal Wavelets of Maximum Coding Gain through Pseudoframes for Subspaces
A method for designing a signal-adapted, two-channel biorthogonal wavelet filter bank that maximizes coding gain is presented using the technique of Pseudoframes for Subspaces (PFFS). At the same time the PFFS model is able to incorporate the requirements of regularity and perfect reconstruction into this design. The coding gain achieved for AR(2) signals can result in a reduction in bit rate o...
متن کاملThe Features of Multiple Affine Fuzzy Quarternary Frames in Sobolev Space
The concept of a generalized quarternary multiresolution struccture (GQMS) of space is formulated. A class of multiple affine quarternary pseudoframes for subspaces of 2 4 ( ) L R are introduced. The construction of a GQMS of Paley-Wiener subspaces of 2 4 ( ) L R is studied. The sufficient condition for the existence of pyramid decomposition scheme is presented based on such a GQMS. A sort of a...
