Abstract :
An optimization technique is presented for the design of multiplierless two-channel linear-phase finite impulse response (FIR) filter banks which yield good filtering performance and nearly perfect signal reconstruction. The filter coefficients are represented by a canonic signed-digit (CSD) code. When applied to image subband coding, this technique provides an easy way to design low-complexity analysis/synthesis filter banks for high-performance codecs. Examples concerning the design of filters and the application to image subband coding are given
