[Insight-developers] proposal: enhancing wrapitk's filter coverage during (one of) the next tcon

[Luis Ibanez]

Hi Gaetan,

This is an Excellent idea !

Thanks for taking the initiative.

A proposal Wiki page has been added to the 2008 section
http://www.itk.org/Wiki/ITK_Oversight_Committee#2008

Direct link:
http://www.itk.org/Wiki/Proposals:Increasing_WrapITK_Coverage#List_of_Unwrapped_Filters

With the content of your email,
including the list of non-wrapped filters.

Please feel free to modify.


The topic has been added also to the Tcon agenda for Friday:

    http://www.itk.org/Wiki/Agenda%26Status_100108

Instructions on how to join the tcon are available at:

   Thanks


      Luis
