A Nonlinear Multiwavelet Transform Based Signal Denoising Method
Xin Wang · Acta Simulata Systematica Sinica · 2003
In this paper, a nonlinear multiwavelet transform based signal denoising method is introduced. Donoho抯 soft thresholding method used in wavelet denosing is effective. But it loses part of edge information in reconstruction due to neglecting singularity detecting. Because of this, we propose a new algorithm that is based on nonlinear multiwavelet transform and combines singularity detecting with soft thresholding. Examples show that the new algorithm is effective.
