<DIV>hello all;</DIV>
<DIV>I got a few pixel values through a normal vector and then I would like to calculate these values derivatives to get maximum gradient magnitude of them. Is there any class for this or ,should I calculate it just my self?</DIV>
<DIV>Does anybody have any knowledge about that?</DIV>
<DIV>Thanks </DIV>
