Hi Martin,

nice port to scala! :-)

I am going to spend some time on JWave soon; want to recheck and rehack the stepping methods. Probably I am going to pull the repsository to github.

When I start coding I can also have a look to the 'incremental algorthm'.

Cu soon - around two weeks.

Hi Christian,

nice to hear from you :D It would be cool to sync on the incremental stuff! I'm not a wavelet expert and haven't completely understood the approach...

Cu soon! Martin

Hi Martin,

I am back on JWave but you might be not so happy about it; I changed a lot! :-p

I spent half a day on JWave and rebuild and refined a lot of stuff, even split the code running pure orthogonal filters to a code allowing now for non orthogonal filters; see BiOrthogonal_1_3.

Hope that is not so demotivating for you because there is a lot of work to match your port. :-/

I am going on to implement several more filters and afterwards I will code the decomposition and reconstruction in steps, and your request of the "incremental" algorithm, if I'll understand it. ;-)

best regards Christian

Hi Christian,

if I understand the changes I guess it won't be too hard to forward them to Scave. Did you already push your commits somewhere? On Google Code the most recent version is r111. I would be happy to join you for the incremental algorithm :) It would have to be during the week after work though (maybe starting at 18:00 Berlin time).

Best regards Martin

Hi Martin,

oh I am sorry, my changes on JWave are already available via github.com: https://github.com/cscheiblich/JWave

Yeah, let's do the incremental algorithm together; time is not a problem. However, I want to fix the stepping algorithm first and then we can switch over to incremental.

Best regards Christian

Hi Christian,

just drop me a line once you're ready to go :)

Hi Martin,

I will do so but it will take its time. :-)

:+1: incremental wavelet is a game changer for real-time time series analysis.
