How about measuring the centre of mass for each particle and then draw a circle at each of the co-ordinate pairs (this could be done in a new image with the same dimensions)? Use 'Analyse Particles' to add all particles to the ROI manager. You can then use multi-measure to get the co-ordinates of the centre of mass for each particle and use a loop to draw circles at each co-ordinate.
This would at least solve the first part of your question. I can't really help with the analysis of connectivity. Sorry.

Hi guys,
It's me again :) I have a question regarding to minkowski functionals.
Please see the image below. Firstly, I want to reduce all the black particles to black circles with a same radius and then use imageJ to calculate the connectivity between the particles. Next, I would like to change the size of the circles (increase the radius) to several different values and then calculate the corresponding connectivity between the particles.
However, I am having problem to change all the particles to circles with same radius (and of course calculating connectivity).

Could someone help me with it?
Thank you so much.
