Abstract

Based on the wavelet transform, the ways and process of wavelet de-noising are presented in the paper. The detail experimental results show that wavelet de-noising is better than traditional filtering ways, and the soft-threshold denoising is obviously better than the hard- threshold denoising.

摘要

基于小波变换，本文给出了小波去噪的方法和过程。详细的实验结果表明，小波去噪优于传统滤波方法，且软阈值去噪明显优于硬阈值去噪。
