|Abstract||A passive blind digital image forgery detection method
was proposed in this paper. Basic defocus model shows that
image patches with similar distances to the lens have similar blur kernel sizes. This consistency is broken in image
forgery as the result of possible blurring and different imaging conditions. Our forgery detection technique uses local
blur estimation at each edge pixels to exposes the defocus
blur inconsistency. Experiment results of tampered images
from real law cases show the effectiveness of our technique.|
