I see no objection that a generic function of OTB migrate to ITK. We already 
did such contributions by the past and after all, we benefit a lot from ITK in 
OTB, so it is just paying back.

However, I am concerned about 2 things :


1)      What would be very bad is to duplicate code between ITK and OTB. If ITK 
is to integrate the wavelet code, it should be removed from OTB (we can leave a 
proxy class for backward compatibility).

2)      CNES is not the copyright owner of the Wavelet code. Gregoire Mercier 
is (as stated in the header files). So I am not in position to agree or 
disagree on anything regarding republishing this code under a different 
licence. You must ask the copyright owner.

We are planning to change OTB licence to Apache 2.0 quite soon, so there will 
be no more licence obstacle. However, my first point is still valid as a rule 
of thumbs : please do not duplicate code.

Regards,

Julien Michel

Hello! I am looking for implementation of wavelet transform in c++, and found 
your nice code about it.

I wonder if it is possibly to adapt and submit your wavelet approach to ITK, 
ITK license is not GPL though.
I just wanted to ask you if I can reuse your code in a ITK submission. For my 
case including a OTB dependency just for the wavelet transform is a bit too 
much.
Thanks for your time.

OTB code is licensed under CeCILLv2 license. see full text here - 
http://www.cecill.info/licences/Licence_CeCILL_V2-en.html
I suggest you read the full article first.
You must also check with ITK about putting code under CeCILLv2 in their source 
tree.
