Point Values and Normalization of Two-Direction Multi-wavelets and their Derivatives
Fritz Keinert, Soon-Geol Kwon · Kyungpook mathematical journal · 2015
A two-direction multiscaling function φ satisfies a recursion relation that uses scaled and translated versions of both itself and its reverse.This offers a more general and flexible setting than standard one-direction wavelet theory.In this paper, we investigate how to find and normalize point values and derivative values of two-direction multiscaling and multiwavelet functions.Determination of point values is based on the eigenvalue approach.Normalization is based on normalizing conditions for the continuous moments of φ.Examples for illustrating the general theory are given.
