Measuring volume between clusters of particles

Good Afternoon Everyone,
I have a cluster of particles that have spaces in between them. I have to be able to determine the total volume of the spaces (pores) between these particle clusters. Can someone please tell me how to do this in Image J ?

Thank you very much.

Measuring volume between clusters of particles

Hi Geology Guy

I'm doing the same thing with soils. If you invert your image then your pores become particles and you can analyse them as particles (assuming your image is thresholded and your pores currently have a value of 0 and your solid has a value of 255).

Good Afternoon Everyone,
I have a cluster of particles that have spaces in between them. I have to be
able to determine the total volume of the spaces (pores) between these
particle clusters. Can someone please tell me how to do this in Image J ?

Thank you very much.

Kathy thank you very much for your reply. I understand what you mean perfectly. The only thing I just have not figured out is exactly how to do the inversion you talked about in image J. Do you mind telling me? Also what type of threshold did you use because there are about 7 different thresholding methods. Thanks a lot for responding on time.
