Abstract :
Presents a systematic method to construct two dimensional spatial-varying filter banks that preserve the perfect reconstruction property. These filter banks are constructed from arbitrary two dimensional (separable or nonseparable) local perfect reconstruction FIR filter banks on different rectangular regions, where overlaps between neighboring regions are used to eliminate the blocking effects. A numerical example is given to illustrate the theory
