Research on Denoising of Deformation Monitoring Data by Improved Wavelet Threshold Function

基于小波分析中传统的阈值函数,结合其他学者提出的小波阈值函数,提出一种改进的小波阈值函数,并将其应用于变形监测数据的去噪处理。理论分析和算例表明,新的小波阈值去噪函数能够有效去除噪声。

Based on the traditional threshold function in wavelet analysis,combined with the wavelet threshold function proposed by other scholars,this paper further studies and analyzes the practical application.We propose a new method:denoising the deformation monitoring data with a new wavelet threshold de-noising function.Theoretical analysis and examples show that the new wavelet threshold de-noising function can effectively remove noise and has good denoising effect.
