Hi,

you can try some simple preprocessing techniques, before thresholding, but these depends mostly on the images you have.

I did the following: 1) image resizing (fx=0.3, fy=0.3) 2) convert to grayscale 3) apply median filter (kernelsize=9) 4) Ostsu filtering

The result is than:

on this you can apply a simple blob detection
