APPLICATION OF THE FAST WAVELET TRANSFORM METHOD TO COMPRESS ULTRAVIOLET-VISIBLE SPECTRA

Data compression methods based on the fast wavelet transform and the m ultiresolution signal decomposition algorithms were devised and applie d to ultraviolet-visible absorption spectra. Wavelet functions of the Daubechies type were employed for the purpose. In addition, two data p retreatment procedures were proposed and used to cope with the side-lo be problem. The performance of these methods was evaluated by using bo th synthetic and experimental data. It was found that the storage spac e of the spectral information under study can be reduced significantly by using the suggested methods with good-quality spectra generated fr om the compressed data.
