[Insight-users] Design Issues: Registration, Pointset's, and multivalued cost functions

[Luis Ibanez]

Hi Haiyong,

No, you can't use single value optimizers with the current

            itkPointSetToPointSetRegistrationMethod
            itkPointSetToPointSetMetric


However,

You can easily clone these two classes, by copy/pasting
the files, renaming them, and replacing internally the string

               "MultiValue"

with

               "SingleValue"

It should take just some minutes to do so,

Once you have those cloned classes, you should be
able to use them with single valued optimizers.

Note however, that a single valued optimizer works
on a resuded amount of information, and therefore
it may take longer to converge than a multi-valued one.


Please let us know if you run into any problem.



BTW: Once you are done, you may want to share
the resulting classes with the ITK community,
by posting them to the Insight Journal.    :-)



      Thanks


          Luis
