Abstract
In this paper the accelerated algorithm of a calculation of Discrete Cosine Transform (DCT), widely used in the practice of the conversion of graphic images, is considered. We investigate the process of the calculating DCT by means of additive formulas. The application of this formulas allows to obtain the very fast computing schemes, which are so necessary for real time systems. In this article is discussed the algorithm, in which the computational process it is process of the algebraic summing basic function samples taken at certain points of the interval independent variable. The conception of the accelerated calculation of DCT is considered on example of real graphic images. The presented algorithms are oriented first of all on use for the analysis of discrete and analog signals and image processing in real time. Additive algorithm for image processing are presented in meta language.
