If you have over-segmentation problem, you can try to hit "No" at :
"Automatically calculate size of smoothing filter for declumping"
"Automatically calculate minimum allowed distance between local maxima"
Then increase the values in :
- "Size of smoothing filter"
- "Suppress local maxima that are closer than this minimum allowed distance"
The values to input there should somewhat reflects the usual size of one (01) aggregate.
Hope that helps.
