Hi,

a ImageJ noob here.
To the point: I have to measure the intensity of white pixels on black background. The white pixels are in circle form. I need the intensity of the (white) pixels in the circumference of the circle ( I think this is called "radial intensity distribution"). Has someone understood what I mean...I know that this was already discussed in the mailing-list but I couldn't understand what I must exactly do.

I would be happy of any suggestions.

Cheers
