Fill bubbles with different colors based on their area

Hello

I have stack of binary images with bubbles, I want to fill the bubbles with different colors based on their area. BioVoxxel plugin does this for single image but it can’t handle stacks. Plus I am only interested in area and not any other morphological parameter. Any suggestions?

Warm regards

When you are looking at the bubbles in 3D, you will be analyzing the volume and not the area.
Look into the 3D ROI Manager @ThomasBoudier has written.
He has a few macro functions in this page:

I think the one you are after is this macro which colourises the object based on their volume:

Thank you for your replay and sorry for delay in response.
My image is actually a 2D image and therefore specifically looking to color the objects (bubbles in my case) based on area. Attaching a sample image for your reference.

Thanks again.

You can do this using a macro. The following example fills the objects in the Blobs sample image with their area. It also labels the objects with their area.

  run("Blobs (25K)");
  setAutoThreshold("Default");
  setOption("Area", true)
  run("Analyze Particles...", "  show=Overlay display clear");
  run("32-bit");
  maxArea = 0;
  for (i=0; i<Overlay.size; i++) {
     area = getResult("Area", i); 
     Overlay.activateSelection(i);
     setColor(area);
     fill;
     Roi.setName(""+area);
     if (area>maxArea) maxArea=area;
  }
  setMinAndMax(0, maxArea);
  run("Ice");
  Roi.remove
  run("Labels...", "color=white font=9 show use draw");
  run("In [+]");
