Measure for Determining Point Correspondence( $\kappa _{mod}$ ):

We test the effectiveness of our technique for estimating correspondences through the shift $\lambda_l$ . Figures 2 and 3 show the inverse Fourier spectrum of the ratio $\kappa_{mod}(l, 1) / \kappa_{mod}(0, 1)$ , when the shifts aligning corresponding points in the two affine views are 150 and 300 respectively.

**Figure:** Graph showing the amplitude of the IDFT of $\frac{\kappa_{mod}(l, 1) }{ \kappa_{mod}(0, 1)}$ against the shift for an affine homography when the synthetic shift is 150.
