In this paper, authors present a formal description of the algorithm for the construction of N-parametric equations, which provides the attainment of any set of dilation coefficients from a set of N angles that sum π/2. These coefficients can be used to construct any dimensional Wavelet filter bank to be applied to analysis and reconstruction of specific(More)
