I'm pretty much stuck with it now, I'm unable to find either source code for the wavelet transform I need (Gabor Wavelet Transform) or a clear explanation of the method to implement it. I've learned the math behind it pretty well, however this deals with the mathematical analysis of its convergence and invertiness, it has nothing on how do I go about doing the implementation. My friend picked up a book by Mallat and is reading it, I'll take it near the weekend and read it too. I hope it has something to hint about the implementation.

I've finally succeeded in embedding Python into LyX, it was pretty simple in the end, However I found out that LyX doesn't have a simple way to export various queries, it has an export for actions like "word-forward" and "file-new" but nothing like "character-insert".

Anyhow, Lars (the LyX project overlord) decided that since LyX is kinda destabilized, he doesn't want to integrate this work or to continue working on it until LyX is stabilized for it's 1.2.0 release. I probably better get back to finish the InsetGraphics widget I was working on so far (the widget is mostly finished, the support stuff isn't).
