Hello, I'm quite new to imageJ, but like a lot of what I'm seeing. I've been trying to automatically determine the area of a number of objects that have been outlined in photoshop with different gray values (8bit). Each gray value denotes a certain species. When I import the tiff into ImageJ I can outline all objects and determine their surface area, perimeter, etc.

However, the objects are non-filled, but only surrounded by a line and I'd like to also fill them automatically with the gray value of the surrounding line.

Later on, I'd like to also swap the gray values with fixed colours.

I'm not sure this is possible in ImageJ, but I see so many different macros/plugins/etc that I can't imagine it's not.

Is anybody able to give me some guidance here? Thanks for any help.

Cheers,
Erik
