Abstract

This correspondence deals with suboptimal multiplierless perfect reconstruction quadrature mirror filter (PR-QMF) solutions. It is shown that multiplierless PR-QMFs perform comparable to or better than the known filter banks and discrete-cosine-transform-based (DCT-based) image coding techniques objectively and subjectively. They are very efficient to implement on very large scale integrated (VLSI) systems. These PR-QMFs might find uses in real-time image and video coding and other applications
