Orthogonal Two-Direction Wavelets of Order 2 From Orthogonal Symmetric/Antisymmetric Multiwavelets

Abstract

A method for recovering Chui-Lian's orthogonal symmetric/antisymmetric multiwavelets of order 2 from orthogonal two-direction wavelets of order 2 was proposed by Yang and Xie. In this paper we pursue the converse, that is, we propose a method for constructing orthogonal twodirection wavelets of order 2 from orthogonal symmetric/antisymmetric multiwavelets of order 2.
