Area measurement of a complex halo-shaped item

Hi,
How can I determine the area of a halo-shaped item in a way that only the black area of the item is represented (picture attached)? “Analyze particles” takes the whole outer boundary into account, including “holes”.
I have searched this trough forums but I can’t come up with a straight-forward solution.

Thanks!

You’ll want to use “Create Selection” instead of “Analyze Particles”… give it a try and let us know if that gives you the results you expect.

Insertske8,
As etarena suggested, but you could also try Edit > Invert and then analyze particles. You may have to Process > Binary > Make Binary if the image requires it for analysis.
