Multiplierless suboptimal PR-QMF design

This paper searches for the suboptimal multiplierless orthonormal PR-QMF solutions. It is shown that there are multiplierless PR-QMFs and they perform comparable or better than the known filter banks and DCT based codec for the objective and subjective tests performed. They are very efficient to implement on VLSI. It is expected that these PR-QMFs will find their applications in real-time image-video coding.
