摘要：Photocopy documents are very common in our normal life. People are permitted to carry and producephotocopied documents frequently, to avoid damages or losing the original documents. But this provision ismisused for temporary benefits by fabricating fake photocopied documents. When a photocopied documentis produced, it may be required to check for its originality. An attempt is made in this direction to detectsuch fabricated photocopied documents. This paper proposes an unsupervised system to detect fabricationin photocopied document using texture features. The work in this paper mainly focuses on detection offabrication in photocopied documents in which some contents are manipulated by new contents above itthrough different ways. A detailed experimental study has been performed using a collected sample set ofconsiderable size and a decision model is developed for classification. Testing is performed with a differentset of collected testing samples resulted in an average detection rate of 89%.
