Streszczenie
Ascertainment of the generation (i.e. 1st, 2nd, 3rd generation etc.) of a photocopy of a (potentially manipulated) document is a great challenge to the forensic document examiner, and furthermore such a finding is useful in trying to establish whether the photo - copied document has been manipulated. In the present study, an attempt has been made to tackle this type of problem by using the image processing technique.
