You can try either median filtering or -morphology close or open (not sure which as it depends upon whether white on black or black on white), I alway try both to make sure which is correct. But I think for your image it is close.

Basically are black spots in white background, in tif images in two colors format, I understand Morphology option, but i can't understand how can i do it?

thanks
