Abstract
The statistical error of correlation measurement of the shift is estimated using the binary image model. The influence of image properties on the accuracy of subpixel measurements of the position of the maximum of the correlation peak is studied. Recommendations for the choice of parameters of the image and correlation algorithm are given.
