[Insight-users] applying filters within a region

[Luis Ibanez]

Hi Hari,

You can use the RegionOfInterestImageFilter
http://www.itk.org/Insight/Doxygen/html/classitk_1_1RegionOfInterestImageFilter.html

in order to extract a region from your large image.
Then connect the output of this filter to the
processing pipeline that you want to experiment with.

Whenever you need to replace the output into the original
location in the large image, you use the PasteImageFilter
http://www.itk.org/Insight/Doxygen/html/classitk_1_1PasteImageFilter.html


Regards,


    Luis
