[Insight-users] Filter and SetRequestedRegion

[Luis Ibanez]

Hi Arnaud,


You may want to look at the following filters:

1) ExtractImageFilter
http://www.itk.org/Insight/Doxygen/html/classitk_1_1ExtractImageFilter.html


2) RegionOfInterestImageFilter
http://www.itk.org/Insight/Doxygen/html/classitk_1_1RegionOfInterestImageFilter.html



    Regards,


       Luis
