Design of Double Density Wavelet Filter Banks
Ashoka Jayawardena
Abstract:We look at the design of oversampled filter banks and
the resulting framelets. The framelets we will design,
will have improved shift invariant properties over decimated wavelet transform.
Shift invariance has applications in many areas particularly denoising
and coding and compression. Our contribution here is on filter bank completion.
We will develop factorization methods to find wavelet filters from given
scaling filters.
