[Insight-users] Restrict image processing to a smaller region

[Chr. Rossmanith]

Thank you, now I finally have my application working. How could I test 
that a filter really restricts itself to the requested region? If I add 
the medianFilter to the viewer as a forth image the whole image has been 
processed. But that might be because the viewer requests the whole image...
