Design of reversible subband transforms using lifting
Michael D. Adams, A. Antoniou · 2002
Presented is a simple yet highly effective method for designing a good reversible version of any linear subband transform. First, the lifting factorization is introduced as a means to generate many reversible versions of a particular transform. Next, a simple metric is described which predicts the accuracy with which a reversible transform can approximate its parent (linear) transform. This metric is then used as the basis for an iterative design technique. A design example is presented to demonstrate the effectiveness of the method.
