| Abstract: | A new method for rotation invariant joint transform correlation,based on SDF and phase shift power subtracting,is presented. The method uses spatial SDF as the reference function of the displayed input scene and phase shift power spectrum subtraction,the proposed joint transform correlation is able to provide an image rotational inivariance and high correlation discrimination.In this paper,the simulation results are given. |

| Keywords: | joint transform correlation synthetic discriminant function power spectrum rotational invariance |
