Adding color to selected areas in ImageJ

Question

I want to measure the area of a group of clumped cells with blurred margins. I cannot set a threshold and measure the ROIs as the edges are not clear. I have to manually select the ROIs. I would then like to color in the ROIs of same area with one color so that it is easy for visualization. I want to show that that in my tissue sample there are cells of different sizes.

Please suggest how I can fill the ROIs with the same area with a color. Is there a better way to do this?

Thanks

Answer 1

There's a macro called ROI Color Coder that colors measured ROIs according to size. That might be close to what you want.

The easiest way to add it to ImageJ is to use the Fiji distribution of ImageJ and activate the "BAR" update site. That way you get any updates automatically.

Check out the ImageJ forum too -- it's a good place to get answers about using ImageJ.

Hope this helps.
