Abstract

In the paper there are presented: the mathematical background of 1D and 2D signal expansion into wavelet series and the algorithm for such expansion in the form of discrete wavelet transform.

The techniques for constructing orthonormal wavelet basis with compact support and their relation to subband filtering of digital signals, are described. There are included examples of wavelet representation for images and its applications in compression for archivization and progressive transformation.
