Abstract
The paper presents a method for the design of quadrature mirror filters. A new frequency weighted stopband energy function is introduced, which leads to considerable flexibility in the design process. Unlike other techniques which involve searches and nonlinear optimization, the formulation reduces the design equations to an eigenvector problem. The resulting filters are regular and have additional desirable properties as discussed in the paper. Also considered is application to pyramidal coding of images, which together with DPCM and PCM, leads to high compression ratios
