Approach to wavelet transformimplementation: wavelet-like filter banks
Lik‐Kwan Shark, D. Qi · Electronics Letters · 1997
The authors present a new method for the design of wavelet-like filter banks using arbitrary lowpass filter response functions, thereby providing a flexible alternative to the implementation of the wavelet transform. The proposed wavelet-like filter banks are shown to offer superior reconstruction performance and possess the property of almost linear phase.
