VARIANTS RESEARCH OF LIFTING SCHEME PREDICTION STAGE REALIZATION WHEN SOLVING THE SOUND COMPRESSION TASK
Read the full article ';
Comparison of different realizations for wavelet transform lifting scheme prediction stage on the basis of three different functions: Haar’s, linear and polynomial – is carried out. An audio signal and financial time series are chosen as the analyzed data. The lifting scheme and the concise description of its main stages are presented. The results of different prediction variants are analyzed and their quantitative assessment is given. The conclusions about the function complexity influence on different types of signals prediction results are made.
