Multiwavelet Preelters I: Orthogonal Preelters Preserving Approximation Order P 2

چکیده
In applications using multiwavelets there is a necessary step of associating a given discrete signal with a function in the scaling function space V 0. This association is equivalent to including a preelter and a posttl-ter for the lterbank determined by the underlying multiwavelets. We give a construction for FIR orthogonal (paraunitary) preelters that preserve the approximation order of a given arbitrary scaling vector with approximation order p 2. We give several such preelters for the DGHM multiwavelets.

متن کاملSignal Preprocessing of Multiwavelets
Orthogonal wavelet bases have been developed using multiple mother wavelet functions. Applying the discrete multiwavelet transform requires the input data to be preprocessed to obtain a more economical decomposition. Four characteristics of a preprocessing method are presented: length, degree, orthogonality and frequency response. A minimal preelter is deened to have length one and highest atta...

This report is contained in the compressed postscript le 2023.ps.Z. Abstract We present results about classes of preelters that may result in similar model estimates by use of the classical least-squares prediction error identiication methods. It will be seen that...
متن کاملOptimal prefilters for the multiwavelet filter banks
This paper proposes a method to obtain optimal 2-order approximation preserving prefilters for a given orthogonal unbalanced multiwavelet basis. This procedure uses the prefilter construction introduced in [3]. The prefilter optimization scheme exploits the Taylor series expansion of the prefilter combined with the multiwavelet. Using the DGHM multiwavelet with the obtained optimal prefilter, w...
متن کاملOn the Use of \nulling" Filters to Separate Transparent Motions
Transparent motions can be isolated in the Fourier domain, using derivative preelters that selectively null the spatio-temporal energy consistent with the gradient constraint imposed by each component velocity. We use these \nulling" preelters to robustly compute the support a particular velocity has at a point despite other velocities that may also be present at that point. Images are decompos...
