The lifting scheme: A construction of second generation wavelets
W Sweldens - SIAM journal on mathematical analysis, 1998 - SIAM
We present the lifting scheme, a simple construction of second generation wavelets; these
are wavelets that are not necessarily translates and dilates of one fixed function. Such …

The lifting scheme: A custom-design construction of biorthogonal wavelets
W Sweldens - Applied and computational harmonic analysis, 1996 - Elsevier
We present the lifting scheme, a new idea for constructing compactly supported wavelets

Factoring wavelet transforms into lifting steps
I Daubechies, W Sweldens - Journal of Fourier analysis and applications, 1998 - Springer
This article is essentially tutorial in nature. We show how any discrete wavelet transform or
two band subband filtering with finite filters can be decomposed into a finite sequence of …
