| Abstract: | 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. |
