Detection of Free-Form Copy-Move Forgery on Digital Images

Figure 1

Some example experimental images. (a) An original image from FFCMF dataset. (b) Copy-move mask for (a). (c) Forgery image which is acquired using (a) and (b) and then exposed to JPEG compression with a quality factor of q = 85. (d) Output image for (c). (e) An original image from CoMoFoD dataset. (f) Copy-move mask for (e). (g) Forgery image which is acquired using (e) and (f) and then exposed to Gaussian filtering followed by JPEG compression with a quality factor of q = 70. (h) Output image for (g). (i) An original image from CoMoFoD dataset. (j) Copy-move mask for (i). (k) Forgery image which is acquired using (i) and (j) and then exposed to JPEG compression with a quality factor of q = 55 followed by Gaussian filtering. (l) Output image for (k).
