Abstract
This article discusses the identification of digital images in the map of the background emission of Universe microwaves developed on the basis of data from the European Space Agency telescope Planck upon applying a simulation of parameter z from the Doppler effect formula and the theory of covariance functions. The value of the Doppler parameter z shows an approximate mutual speed of two digital images (objects) with respect to the speed of light in vacuum. For a calculation of values of parameter z, vectors transformed by digital images and the pixels intensity of the white solar spectrum were used. The values of parameter z enabled calculation of the mutual speed of the digital images and the speeds of their movement with respect to the solar system. For calculation of estimates of the covariance functions, the algebraic additions of vectors transformed by the digital images and single vectors were applied. While varying the scale of a digital image, the frequencies of single pixel colours do not change, that is, they remain constant and no impact of the scale variation expresses itself in the calculation procedure of covariance functions. For the identification of images, the spectrum of RGB format was used. The average values of parameter z in the Doppler formula were calculated according to the formula created on the basis of expressions of cross-covariance functions of the algebraic addition of relevant transformed vectors and single vectors. The mutual speed of the movement of images of a part of the Universe was established. The calculation data were obtained using MATLAB-based computer programmes.
