FIELD: information technology.
SUBSTANCE: adaptive definition of the wavelet-basis for discrete wavelet transformation is possible through selection from a library or calculation. The wavelet-basis can be defined using: characteristics obtained using statistical, correlation and spectral analysis methods for blocks and sub-bands of blocks of the initial image; image block reconstruction error.
EFFECT: fewer transmitted or stored data through adaptive definition of the basis function for discrete wavelet transformation for initial image blocks.
