[Insight-developers] A possible class submission

[Luis Ibanez]

Hi Samson,

Thanks for contributing your new image
metric classes to ITK.


Please do the following:

1) Submit an experimental build from the
    machine where you have these new classes.
    Make sure that the experimental includes
    the two test associated with these new
    classes.

2) Once the experimental build appears on
    green on the dashboard, please send us
    the files and we will commit them into
    the repository.

3) In order to acknowledge the credits to
    class authors, please add the credits
    that you consider appropriate to the
    documentation of the class. This credits
    will then show up in the Doxygen
    documentation of the class.


Please let us know if you have any questions
or concerns.


Thanks


    Luis
