Anurag Nishad

Hi Deepanshu Kumar ,

If you share the image we might be able to help you.

Deepanshu Kumar

Anurag Nishad. It is attached.

You can use ImageJ. Here, ( https://www.youtube.com/watch?v=JQAZ--c9YfI )you can find a simple demonstration.

This I have already seen. We are not able to do thresholding of our image and image J will not cover all the particles

Pierre Caulet

I'm afraid your particles are much too agglomerated to do anything. I'm pretty sure that no usual image analysis procedure will be able to separate them.

When working on that type of dispersion/suspension, I generally dilute them, further disperse them under ultrasonics and finally spin coat them on a SEM stub, so that particle dispersion is as optimal as can be and they become single objects.

Not even sure machine learning IA may help...
