Originální abstrakt

This paper describes implementation of the Discrete Cosine Transform (DCT) algorithm to MATLAB. This approach is used in JPEG or MPEG standards for instance. The substance of these specifications is to remove the considerable correlation between adjacent picture elements. The objective of this paper is not to improve the DCT algorithm it self, but to re-write it to the preferable version for MATLAB thus allow the enumeration with insignificant delay. Method proposes in this paper allows image compression calculation almost two hundred times faster compared with the DCT definition.
