Support Center Support Center. Symmetric orthonormal scaling functions and wavelets with dilation factor 4. In this work, we present a family of compact, biorthogonal wavelet filter banks that are applicable to the Body Centered Cubic BCC lattice.

Note that g 1 is symmetric and g 2 and g 3 are antisymmetric. This article has been cited by other articles in PMC. Improved multiresolution analysis transforms for satellite image compression and reconstruction using evolution strategies Brendan J. MooreMichael R. In this section, a class of 4-band symmetric biorthogonal wavelet filters for fast calculation is designed, and the corresponding wavelet filters are constructed.

Biorthogonal Bases of Compactly Supported Wavelets

Open in a separate window. Conclusions and future work We have constructed a class of 4-band symmetric biorthogonal wavelet bases, in which any wavelet system the high-pass filters can be determined by exchanging position and changing the sign of the two low-pass filters.


The element at the j th row and the k th copactly in G 1 G 1 T can be written as. Browse subjects Browse through journals Browse through conferences. A concrete example with high vanishing moments is also given which leads to highly efficient computations.

Matrix extension with symmetry and construction of biorthogonal multiwavelets with any integer dilation. This paper has 1, citations. China Find articles by Qingyun Zou. The Biotthogonal Shearlet Transform: Multi-band wavelets have attracted considerable attention due to their richer parameter space to have a more flexible time-frequency tiling, to zoom in onto narrow band high frequency components in frequency responses, to give better energy compaction than 2-band wavelets.

Optimal model for 4-band biorthogonal wavelets bases for fast calculation

In this paper, we can construct innumerable wavelet filters with some structure for fast calculation, among which we can select the best ones for practical applications.

We show here that under fairly general conditions, exact reconstruction schemes with synthesis filters different from the analysis filters give rise: It follows from Theorem 3.
