[Insight-users] How to restrict work region of filters

[Luis Ibanez]

Hi Chris,


You can do it with the following Pipeline



          ImageToBeFiltered------------+
                  |                    |
                  |                    |
                  V                    |
    ExtractRegionOfInterestFilter      |
                  |                    |
                  |                    |
                  V                    |
            Your Filter                |
                  |                    |
                  |                    |
                  V                    |
           PasteImageFilter-<----------+



If you have concerns about memory, you can use
the PasteImageFilter as an InPlace filter. So
that the output image is using the same memory
buffer as the ImageToBeFiltered.

Just call the InPlaceOn() method on the Past
image filter. Please not that this only makes
sense if your filter uses the same pixel
type for the input and output images.



    Regards,



       Luis
