| Abstract: | In this paper,we suppose that the image signal and noise are independent two-dimensional homogeneous Gaussian random field with zero mean, they are 2-order dif-ferentiable. The local accuracy formulas of image matching with geometric distortion using mean squared difference algorithm are derived. The effect of geometric distortion and noise on matching accuracy is analyzed. An example and several computational results are given, the validity of the method is confirmed. |
