    Abstract

    This paper considers the problem of reducing the computation time in the formation of a single image based on its individual fragments using the sliding window method. A payoff function is obtained. Numerical simulation helped demonstrating the effect of the measurement error and the window size on the accuracy of determination of the shift coordinates of the fragments. The choice of the form of the functional and the window size is substantiated.
