Abstract

The algorithms for estimating the vector of shift of dynamic image’s fragments are synthesized in the form of discriminators of two types. The first-type ones perform processing of signals in the spatial domain. Others use decomposition of a signal into a spectrum in the basis of orthogonal polynomials. With the aid of analytical methods and of statistical simulation, characteristics of the estimation algorithms are determined depending on signal-to-noise ratio, true value of the shift parameter, and the number of modes to be processed.
