Hello,
please see attached the following image.
i want to detect the small dirt pieces that can be found on most parts of the picture (small dark ones). I tried to filter them with treshholding from an grey image, but that doesnt allow me to only find the small obstacles (tried with binary based on brightness but other elements are too dark).
Any suggestions how to filter those small artifacts?

Try imtophat() or imbothat() then threshold to find a mask. Then use regionfill() to smear in the surrounding region to "erase" the black specks.
