calculating number of particles per cluster

[Hediyeh Malekzad Sani Nobar]

Hello,
I need to analyse several SEM images and calculate number of particles per
each cluster.
I have activated Biovoxxel feature which is for studying clusters but,
still I can not define clusters.
Could you please help me with applying right parameters?
Sample image is attached
Thank you and regards

Good day!

Your sample image is noisy and not very well resolved for this task.

Attached please find a first analysis of one of the clusters.

The cluster was low-pass filtered and then "Find Maxima..." with tolerance
10 was applied.

You may also experiment with bandpass-filtering.

Clusters themselves can be found after massive low-pass filtering.

Good luck

Herbie

Dear Herbie,
Thanks for your email.
I could find maxima after(See attached file: Capture1.PNG) applying
bandpass. You can see the attached image, however, my question is how can I
count number of particles for each cluster automatically.
Because I need to know average number of particles for all the clusters in
this image and another 30 more images that I have. So, as you can imagine I
cant count it manually.
For spread particles, we can do it by analyze>analyze particles, but here I
need to do it for clusters.
Thank you and regards

As I've tried to explain, it's a two step process:

First get the clusters, then analyze one after the other.

Attaches please fins a segmentation of the clusters.

[Glen MacDonald-3]

The macro filenames appear sorted randomly when opening the Toolsets folder from the ‘>>’ icon on the Fiji toolbar.  Opening the directory from the Plugins>Macro>Install displays the macros properly sorted by name.

2018 MacBookPro, OS10.14.3, IJ 1.52i, Java 1.8_162.  Its been happening for awhile and on other Macs.  
Is this a setting I’ve missed?

regards,
Glen MacDonald
