Space images processing
The developed design procedure allows obtaining the degree of graphic presentation compression improvement from 5 to 15 % with respect to the wavelet methods. Time for coding and decoding can vary in wide limits and can be adjusted for specific devices.

Saving of time for the main decoding procedure is comparable to Уthe fastestФ for today technology JPEG and equals 30-40%, that depends on the realization: personal computer or program-logic integrated circuits.
