Abstract
It is shown that the energy image spectrum can be described by a set of spectral moments used as an instrumental spectrum estimate in solving some problems of image analysis and classification. An analytical relationship between the power characteristics of signals in the space and frequency regions, which extends the Rayleigh theorem to moments of any arbitrary order of the function of two variables, is obtained. It is proved that a moment of any high order in the frequency domain is always in correspondence with the second-order moment in the space region. A spectral moment calculation algorithm is presented.
