Dear list,
for quite some time I've kept the software I wrote for my PhD spinning on my
hard drive. It's a library that provides two main functionalities:
- Sampled continuous wavelet transforms, along with two flavours of continuous
inverses, currently with Morlet (real and complex), Paul,
Daubechies-Grossman-Meyer-, and Mexican Hat wavelets.
- Sampled continuous matrix wavelet transforms of functions R->R^n - as opposed
to the R^n->R functions occuring with multi-wavelets; again with several
flavours of inverses.
I'd really like to make it available under the GPL, but copyright issues
prevent me from publishing the software as is, so some kind of thorough rewrite
is due.
I'm not sure, however, how to proceed. On the one hand, there already are
several wavelet toolboxes, but none of them does it all, and hardly any one of
them does arbitrary inverses.
Moreover, I'd like to get rid of any procedural interfaces, because they cause
some headaches related to memory management that an object oriented approach
would simply make disappear, but then again, I haven't done a lot of
oo-programming in Octave, and I wonder if there are any pitfalls I'm not yet
aware of?
Finally, I don't have any clear concept let alone a roadmap for pushing all the
heavy lifting to an external library. Since all the stuff has the chance of
being used in closed-source production code, too, I'd like to put it in a
library I can just re-licence under the GPL in the long run, but what would be
the best way to do it? I am admittedly not the biggest fan of C++, but there is
a Java package on Octave-Forge, and I already wrote some java wrappers for
FFTW. Can anyone perhaps comment on the maturity of the Java package?
Kind regards,
Alex
