Abstract
A new regular M-band orthogonal wavelet filter bank (OWFB) is designed by inserting zeros into the filter transfer functions, which improves the characteristics of the frequency magnitude response. In an application of the sub-band coding of a still image, the new OWFB improves the PSNR by ~1 dB in the reconstructed image over the existing OWFB at the same bit rate
