Exposing Digital Forgeries by Detecting Image Blurred Mathematical Morphology Edge
Yixian Yang · Dianzi xuebao · 2008
A novel image forensic detection scheme for digitial images was proposed in this paper,which can determine whether an image is tampered or not using blue operation.The difference between artifical blur and defocus blur can be indicaded by edge processing using homostasis filtering and mathematical morphology.The blue tampered regions can be detected by blur edge analysis.Experimental results demonstrate the effectiveness of the proposed scheme.
