Analysis and synthesis of discriminators of shift of image’s dynamic fragments in the spatial and spectral domain

Yu. S. Radchenko, Ye. V. Ovchinnikov

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.
