Abstract
The influence of the phase of conjugate quadrature filters (CQF's) on the performances of a subband coding scheme is analyzed. When the filt er length is short, the phase characteristic has virtually no influenc e on the peak signal-to-noise ratio (PSNR)/bit rate results and on the performance of postprocessing algorithms such as edge detection.
