Thread Subject: dependent threshol

hi all


i have this question. i complete project in on line/off line signature verification
but now my problem is how to choose a threshold for every person, can any one help me or give me an advise in this. my probelm is that forged and genuine signatures are very close in some times and too different in another time
so this for me very difficult to classify them into two classes

Sorry, one Ph.D. is enough. I'm not going to do yours for you. This
is a very challenging problem and not one that can be answered in such
a forum.
Good luck with it,

I think I have read that modern signature verification depends not just
on the final visual representation but also upon the measured pressure
as the signature is written.

Q = quotation(rand);
if isempty(Q); error('Quotation server filesystem problems')
else sprintf('%s',Q), end
