Abstract
A method of calculating the discrete cosine transform (DCT) of blocks of pixels of a picture includes the steps of defining first subdivision blocks called range blocks, having a fractional and scaleable size N/2*N/2, where i is an integer number, with respect to a maximum pre-defined size of N*N pixels of blocks of division of the picture, referred to as domain blocks, shiftable by intervals of N/2pixels. The method also includes the step of calculating the DCT on 2range blocks of a subdivision of a domain block of N*N pixels of the picture, in parallel.
