A toolbox for the lifting scheme on 2D quincunx grids and for the computation of moment invariants

File Information
Description

A collection of functions is presented
which includes 2nd generation wavelet
decomposition and reconstruction tools
for images as well as functions for the
computation of moment invariants.
The wavelet schemes rely on the lifting
scheme of Sweldens. Rectangular grids
are split into quincunx grids, also
known as red-black ordering.
The prediction filters include Neville
filters as well as a few nonlinear
ones fairly capable of preserving local
maxima or minima.
The decomposition and reconstruction
functions are called in the style of
the Matlab Wavelet Toolbox.
Many small and a few elaborate examples
have been included, ranging from the
computation of moment invariants to
multiresolution image fusion. Please
see Contents.m for an exhaustive list.
There one finds also a weblink to a
report (in pdf) providing lots of back-
ground information and many references.

Could you also make a 1D lifting scheme for learners like us?
Thank you.
