[Insight-users] areaOpeningImageFilter difficulties

[Gaëtan Lehmann]

Hi,

You won't find that parameter in Richard's original paper. That's a  
parameter I have added to make the area opening filter able to work  
with a component object size in pixels or in physical unit with a high  
precision. When using a number of pixels, you may prefer to used the  
type unsigned long.
Most of the time, the default type should be fine though.
