Optimization of multirate filter banks within the framework of a human visual model
J.A. Lundblad · 1991
A perfect reconstruction filter optimization based on a human visual model is presented. The optimized filters are compared to a set of published filters for coding at a fixed bit rate. A method is suggested for adapting the filters to change in source statistics. This method is applied to coding of intraframe data and residual frame data after motion-compensated prediction.>
