Description

A copy-move image forgery generally refers to copying a portion of an image and re-inserting it elsewhere in the same image, with the intent of hiding undesirable contents or duplicating particular objects of interest. In particular, this thesis deals with copy-move tampering in scanned versions of printed text documents.

The goal of the thesis is to extend an available toolbox with the content-aware creation of copy-move forgeries of scanned text images and enable the automatic generation of semantically meaningful text forgeries.

Prerequisites

Student's interest (first experience) in image processing and/or OCR
