Abstract
In one embodiment, an image processing device for detecting tampering in a document image is disclosed. The image processing device comprises a processor and a memory communicatively coupled to the processor. The memory stores processor instructions, which, on execution, causes the processor to determine an image quality of the document image by analyzing one or more quality features extracted from the document image. The processor is caused to pre-process the document image based on a pre-defined ontology of documents when the image quality is above a pre-defined quality threshold. Further, the processor is caused to segment the pre-processed document image into one or more region of interests based on the pre-defined ontology of documents and detect tampering in a region of interest in the document image by processing each region of interest of the one or more region of interests to detect tampering in the document image.
