Java implementations of the algorithms discussed on this page can be downloaded in the file lift.tar. This file archive contains the directories and files shown below.

lifttest.java lifttest.cpp C++/ C++/interp.h C++/leastsq.h C++/lifting.h lift/ lift/daubechies.java lift/haar.java lift/haarpoly.java lift/liftbase.java lift/line.java lift/poly.java lift/polyinterp.java

The `lift` sub-directory contains Java implementions for the
Haar, line and polynomial interpolation wavelets. These algorithms
mirror the algorithms discussed on the predict
wavelet web page.

The `C++` directory contains a C++ version of the Haar
transform extended with polynomial interpolation (e.g.,
`lifting.h`. This is supported by the interp.h class. The
leastsq.h class is a C++ example of four point linear interpolation.
