Paper Abstract
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 based switching between arbitrarily
designed FBs induces spurious transients into the resulting subbands during the transition. In this paper we
propose a boundary handling mechanism that maintains good frequency response and eliminates the transients
during the transition. We successfully show spatial adaptation between JPEG2000 9/7 and 5/3 FBs to reduce
the ringing artifacts in images.
