【摘要】 Ridgelet变换是信号的一种新的多尺度表示方法,它特别适合于具有线奇异性的二维信号的描述。将小波的自适应阈值去噪方法扩展到Ridgelet域中,应用Ridgelet变换,采用自适应阈值对地震信号进行去噪处理。数值实验结果表明,Ridgelet变换在地震信号去噪方面优于小波变换。更多还原

【Abstract】 Ridgelet transform is a new multi-resolution representation of signal.It is especially suitable for describing the signals with linear singularities.The adaptive wavelet thresholding denoising method used in Wavelet domain is extended to Ridgelet domain.Ridgelet transform is applied to seismic signal denoising by adaptive thresholding.Experiment results show that Ridgelet transform is more efective than the wavelet transform in seismic signal denoising.更多还原
