A linear phase two-channel filter bank allowing perfect reconstruction (image coding)
Hitoshi Kiya, Mitsuo Yae, Masahiro Iwahashi · 2003
Describes a perfect-reconstruction two-channel QMF (quadrature mirror filter) bank, in which the analysis and synthesis filters have linear phases. First, a technique for designing filter banks is presented. Next, the results of two examples demonstrate that the method can lead to good filters although its procedure is very simple; also, this yields filters without multipliers such as the SSKF (symmetric short kernel filter) bank.>
