I have also have some code for SPSA optimization. I found it quite
useful for rigid registration (it seems to be pretty robust). The source
code for a rigid registration application based on ITK is available on 

http://euterpe.tele.ucl.ac.be/Waleo2/vesale/

I would like to compare our implementations of this optimizer.

Regards,

Mathieu.
