You appear to have marked blobs, not scratches. Scratches are long thin marks such as appear near the bottom left of the bright area.

Try a tophat or bottomhat filter, imtophat() or imbothat().

You should also get a better photo. Your setup is horrible. Have you considered using more uniform illumination, board illumination (no line or point sources of light), crossed polarizers (to knock out that specular reflections right where you want to analyze), etc. It's always better to start with a good image than to try to fix us a crappy image afterwards in software.
