Hi there,

I am a new comer.

I'd like to identify the white object within black
background for my photo.

The function of "Analysis->Analyze Particles" works
well to extact black object from white background. But
I left couple of object which is within black
background. I wonder if there is a straight way I can
do by "Analysis->Analyze Particles"

Or I can reverse my original photo, so that the black
and while is reversed. And I extract black object,
which is actually while in the original photo.

thanks,

Michael,
