Abstract
Types of interpolation in calculating the frame-to-frame difference for decreasing the influence of the stationary background when detecting point objects are compared. The comparison is done for an observation system with a photodetector array and an oscillating axis. Methods of interpolation in the presence of a fractional shift (below the photodetector array step) are considered. Computational experiments estimating the efficiency of the methods upon detecting point objects were carried out.
