摘要
小波阈值去噪方法在工程中已得到广泛应用,小波阈值去噪过程中,阈值的选取和处理方法是关键问题。本文介绍了传统的软阈值、硬阈值小波去噪方法原理,在此方法的基础上给出了一种基于小波分析的自适应阈值算法,弥补了软硬阈值函数的不足,通过仿真证明了该方法的有效性。
Wavelet threshold denoising method has been widely used in engineering.the selection and processing method of threshold is the key problem.In this paper,the principle of traditional soft and hard threshold wavelet denoising method is introduced.Based on this method,an adaptive threshold algorithm based on wavelet analysis is given,which makes up for the deficiency of soft and hard threshold function.The effectiveness of this method is proved by simulation.
