Dear all,

I was wondering; the 'fill holes' option in the binary submenu as well  
as filling holes in the image itself helps remove noise from the  
background too doesn't it? I ask this because I get a reduction in the  
background noise in my image when I use it. I was wondering, what is  
the nature of the algorithm? Does it look at the average intensity of  
pixels around or something? Or am I confused somewhere?

Thanks in advance for your help,
All the best for the New Year,
