Abstract :
A new technique is proposed for the design of high-performance quincunx filter banks for the application of image coding. This method yields linear-phase perfect-reconstruction systems with high coding gain, good analysis/synthesis filter frequency responses, and prescribed vanishing moment properties. Examples of filter banks designed with this technique are presented and shown to be highly effective for image coding
