Description

In visual perception, distant objects appear smaller than those close to the observer. To insert an object into an image, determination of size of the foreign object was difficult especially when there was no any reference image. To detect this type of image forgery, we present a perspective-constraint based method, which can find the forgery image without any knowledge of camera parameters. In this method, we can find the forgery image by finding the vanishing point of that image. Then by using SIFT algorithm, we find the forgery region of the given image.
