This method determines first a density conversion condition for the digital image, determines next a gradation conversion condition for the image on the basis of the density conversion condition, modifies the digital image on the basis of at least one of the density and the gradation conversion conditions, and thus creates the reproduced image. The radio controller unit controls operation of a radio cognitive system as a function of the information as to usage of individual bands in the frequency spectrum as derived by the spectrum usage estimator module. Each composite motion recognition window is then passed to a motion recognition model trained by one or more machine-based deep learning processes.
