Development of a software framework for the detection of copy-move text forgeries: analysis of text areas

Supervisor(s)Dr. Svetlana Abramova


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. This thesis concerns the detection of copy-move tampering operations in text documents (e.g., scans of certificates).

The objective is to implement a software framework for the detection of copy-move text forgeries following the approach in Abramova and Böhme (2016). This thesis should focus on the analysis and detection of copy-move operations in text (content) areas of an image. It is closely related to the other thesis that concerns the analysis of text-free, background areas. Both theses require an integration of Optical Character Recognition (OCR) into the processing pipeline.
