Performance Analysis Of An Intraframe Quadrature Mirror Filter Subband Coding System

A subband coding system for high quality video signals suitable for ATM packet communication has been investigated. Monochrome signals at a transmission rate of 0.84 bit/pixel have been simulated: The performances of classical linear phase Quadrature Mirror Filters and quasi-linear phase and minimum phase with perfect reconstruction analysis-synthesis QMF using matched quantizers have given identical results for the 16 coefficients filters; 8 coefficients linear phase filter and matched quantizer perform slightly better than perfect reconstruction ones.© (1989) COPYRIGHT SPIE--The International Society for Optical Engineering.
