Boundary handling mechanism for lifting-based spatial adaptation of filter banks

Boundary handling mechanism for lifting-based spatial adaptation of filter banks

Time/space varying filter banks (FBs) are proved to be useful in building signal adaptive transforms. Lifting factorization of FBs allows to spatially adapt between arbitrary FBs, avoiding the need to design border FBs to complete perfect reconstruction (PR) during the transition. However, lifting b...
