"The paper is devoted to the study of the multi-resolution approach of image compression employing the Haar wavelet transform. In the initial part of the paper the computation algorithm of the Haar transform for signals and images is proposed. Then its orthonormality property is analysed in connection with the preservation of the total amount of signal or image energy using its transform coefficients and following the Parseval's theorem. This property is the used to indicate the extent of possible image compression. The final part of the paper presents two perfect reconstruction conditions in the z-domain applying results to Haar filters." . "22340" . "[25B8B55BEDBF]" .
