Abstract
The accuracy of estimating the shift between two discrete images of the same scene is analyzed in the situation when the shift value is under the sampling step. A new algorithm is proposed for estimating the shift. The algorithm requires a low computational complexity and its estimate errors are small. Results of computational experiments verify its advantages over the known algorithms.
