On a family of orthonormal scalar wavelets and related balanced multiwavelets
Lixin Shen, Hwee Huat Tan · IEEE Transactions on Signal Processing · 2001
For a family of length-4N orthonormal scalar wavelet filters that has been shown to be closely related to symmetric/antisymmetric orthonormal multifilters (SAOMFs), a sufficient and necessary condition is given for their construction. A near-linear criterion is then provided for constructing balanced multiwavelet filters related to these scalar filters. Numerical results are presented to demonstrate the potential usefulness of this criterion.
