Simulation and comparison of wavelet de-noising in MATLAB
Cuifang Zhang · Information technology newsletter · 2008
Wavelet theory has been widely used in signal de-noising with its theoretical completeness.At first,the thesis introduces wavelet property.Secondly,the thesis discusses four methods of signal de-noising: wavelet threshold de-noising,translation-invariant,modulus maximum de-noising and SSNF(spatially selective noise filtration) by theory analysis and MATLAB simulation in detail.Finally,the effects of the methods in de-noising are compared.
