New results on approximate Hilbert pairs of wavelet filters with common factors
Sophie Achard, Irène Gannaz, Marianne Clausel +1
In this paper, we consider the design of wavelet filters based on the Thiran common-factor approach proposed in Selesnick [2001]. This approach aims at building finite impulserespo…
