چکیده
Suppose a real-valued function φ ∈ L2(R) satisfies the following conditions: (a) φ̂(2ω) = m0(ω)φ̂(ω), where m0 is an essentially bounded 2π -periodic function; and (b) limω→0 φ̂(ω) = (2π)−1/2; then the function φ is called refinable or scaling, m0 is called a symbol of φ, and the relation in item (a) is called a refinement equation. Every refinable function generates multiresolution analysis (MRA) of the space L2(R), i.e., a nested sequence

Symmetric Canonical Quincunx Tight Framelets with High Vanishing Moments and Smoothness
In this paper, we propose an approach to construct a family of two-dimensional compactly supported realvalued symmetric quincunx tight framelets {φ;ψ1, ψ2, ψ3} in L2(R) with arbitrarily high orders of vanishing moments. Such symmetric quincunx tight framelets are associated with quincunx tight framelet filter banks {a; b1, b2, b3} having increasing orders of vanishing moments and enjoying the a...
متن کاملFramelets with Many Vanishing Moments
We study tight wavelet frames associated with given refinable functions which are obtained with the unitary extension principles. All possible polynomial symbols generating refinable functions and admitting framelets with a given number of vanishing moments are found. We also consider constructions of (anti)symmetric framelets generated by a symmetric refinable function. We give a few examples ...
متن کاملSymmetric Framelets
We study tight wavelet frames associated with symmetric compactly supported re-nable functions, which are obtained with the unitary extension principle. We give a criterion for existence of two symmetric or antisymmetric compactly supported framelets. All reenable masks of length up to 6, satisfying this criterion, are found.
متن کاملTight and sibling frames originated from discrete splines
We present a new family of frames, which are generated by perfect reconstruction filter banks. The filter banks are based on the discrete interpolatory splines and are related to Butterworth filters. Each filter bank comprises one interpolatory symmetric low-pass filter, one band-pass and one high-pass filters. In the sibling frames case, all the filters are linear phase and generate symmetric ...
متن کاملSymmetry Feature and Construction for the 3-Band Tight Framelets with Prescribed Properties
A construction approach for the 3-band tight wavelet frames by factorization of paraunitarymatrix is developed. Several necessary constraints on the filter lengths and symmetric features of wavelet frames are investigated starting at the constructed paraunitary matrix. The matrix is a symmetric extension of the polyphase matrix corresponding to 3-band tight wavelet frames. Further, the paramete...
متن کاملDesign of symmetric bi-orthogonal double density wavelet filter banks
We look at the design of a class of oversampled filter banks and the resulting framelets. The oversampled property is achieved via an extra subband resulting in Double Density Filter Banks (DDFB’s). We design a class of such filters with linear phase property. We will look at a special class of framelets from a filter bank perspective, in that we will design double density filter banks (DDFB’s)...
