[Insight-users] Levenberg Marquart optimization

[Dawood Masslawi]

Hi Sergio,
Only the ICP examples use the L-M optimizer, however there is a curve
fitting method submitted to the Insight Journal which might help you.
Take a look at this submission to the IJ, http://hdl.handle.net/1926/45
and try to replace their optimizer with the L-M optimizer.
Good luck,
Dawood

Hi Juan,

The IterativeClosestPoint examples of the ITK (Examples\Registration\) use the Levenberg-
Marquardt
 optimizer.
HTH,

Hello All,

I would like to know if somebody has an example on how to use the 
Levenberg Marquart optimizer or specifically how to set up the cost 
function. I haven't been able to find examples.

I'm trying to perform a re-weighted least squares minimization, the 
levenberg Marquart might do it. Any help pointing in the right direction 
will be very helpful.

Thank you in advance,
