Tight frame wavelets with equal norms highpass and bandpass filters
A. Farras Abdelnour · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2007
The paper presents new tight frame dyadic limit functions with dense time-frequency grid. The filterbank consists of one lowpass filter and three bandpass and/or highpass filters. We add the requirement that the bandpass and highpass filters be all of equal norms. All the filters in the paper are FIR and enjoy vanishing moments.
