How to erode a mask

[Nas-5]

Dear all,
 
I have a 3D binary mask and I would like to erode it by one pixel in order to remove the pixels that are at the boundary of the mask and the background. Is there a way to do this in ImageJ? Could you please advise me on this?
 
Many thanks in advance,
Nas

Fiji (http://pacific.mpi-cbg.de/) has an "Erode (3D)" function in
the Plugins>Process menu.
