<p class=MsoNormal>Thanks a lot Luis for that hint! <br>
After checking some books about filters it’s kind of obvious to me now …<br>
<br>
Just one more question to your approach: <br>
After removing the smoothed version from the original image I probably need to
add the result to the original image again (which enhances edges only), at
least this is what the books suggest or is there another way? If I don’t
add it, I get only an edge image…<br>
<br>
