[vtkusers] Cropping out a portion of an image

[Hayden Smith]

Dear vtkusers,
      Thank you very much for the reply. I have attached the image for your kind perusal.The arrow shows the indented portion which I need to extract from the image. As there should be a sharp deviation in gradient at the indented portion, I am thinking whether it is possible to extract that portion  and whether it is possible to do with VTK.
     Please provide me some suggestions.
 
Thanks,
Hayden.

I would like to use the cropped portion for surface reconstruction using vtkImageReader. Please provide me some suggestion how that cropping can be performed using vtk.
