The boundary wavelet and scaling coefficients are those subject to circular filtering operations. This function returns the range of indices which span the interior (or nonboundary) wavelet and scaling coefficients. If approximate zero phase filters are used in the wavelet trsnsform input then the shift factors needed to bring the coefficients to (approximate) zero phase are also returned.
