Can anybody tell me the advantages of the lifting scheme and why it is better then a normal filter bank?
Unlike the convolution, the lifting scheme can
- map integers to integers (CDF 5/3 transform in case of JPEG 2000),
- asymptotically reduces the computational complexity by a factor two,
- can be computed in-place,
- allows to simply treat signal boundaries (periodic symmetric extension in case of JPEG 2000).
