Abstract

This paper proposes a method to realize the lifting scheme of tight frame wavelet filters. As for 4-channel tight frame wavelet filter, the tight frame transforms’ matrix is 2×4, but the lifting scheme transforms’ matrix must be 4×4. And in the case of 3-channel tight frame wavelet filter, the transforms’ matrix is 2×3, but the lifting scheme transforms’ matrix must be 3×3. In order to solve this problem, we introduce two concepts: transferred polyphase matrix for 4-channel filters and transferred unitary matrix for 3-channel filters. The transferred polyphase matrix is symmetric/antisymmetric. Thus, we use this advantage to realize the lifting scheme.
