摘要
This work generalizes the rank 2 (scale factor of 2) orthogonal wavelet sequences of Daubechies to the case of a rank M wavelet matrix. Several equivalent definitions of Nth order vanishing moments for rank M wavelets are developed. These notions are used to find an explicit formula for rank M wavelet scaling sequences with N vanishing wavelet moments (of degree N in our terminology). A full wavelet matrix (scaling sequence and M - 1 wavelet sequences) is constructed, with explicit examples.
