And as this technology continues to evolve it will become increasingly more important for the science of digital forensics to try to keep pace. There is little doubt that as we continue to develop techniques for exposing photographic frauds, new techniques will be developed to make better and harder to detect fakes. And while some of the forensic tools may be easier to fool than PHOTO FAKERY AND FORENSICS 51 FIG. 20. Shown are the original (left) and doctored (right) image. Shown below are the different images at qualities 60–98 in steps of 2.
Computed. The irradiance profiles corresponding to v1 and v2 are given by ! x1 ¼ M v1 ; ! x2 ¼ M v2 ; ! ð52Þ ð53Þ where the matrix M is of the form in Equation 42 (for 3D normals) or Equation 46 (for 2D normals). After subtracting the mean, the correlation between these zeromean profiles is ! corr x1 ; x2 ¼ ! T! x1 x2 ! T ! ! v1 Q v2 ﬃqﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃ ; corr v1 ; v2 ¼ qﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃﬃ ! ! v1T Q v1 v2T Q v2 ð55Þ where the matrix Q for both the 2D and 3D cases is derived in . By design, this correlation is invariant to both additive and multiplicative factors on the irradiance !
The sweaty skin of the basketball player is somewhat shiny, a violation of the Lambertian assumption. In addition, the shoulders and arms of the basketball player provide only a limited extent of surface normals, making the linear system somewhat ill conditioned. 0001 are the left and right pumpkins on the bench. Both pumpkins provide a large extent of surface normals, over 200 , and the surfaces are fairly diffuse. Since the surfaces fit the assumptions and the linear systems are well conditioned, the error between the estimated coefficients is small.
