Abstract :
Consideration is given to the problem of designing a signal-adapted two-band filtering system that has the perfect reconstruction property for application to multiresolution signal coding. A natural optimization criterion for this problem is introduced, and an iterative algorithm for computing optimal filters in lattice form is described. Some simulation results for the application of the technique to image coding are presented
