Multiscale anisotropic diffusion for ringing artifact suppression in geophysical deconvolution data

作者：Boxin Zuo,Xiangyun Hu,Meixia Geng

摘要：Ringing artifact degradations always appear in the deconvolution of geophysical data. To address this problem, we propose a postprocessing approach to suppress ringing artifacts that uses a novel anisotropic diffusion based on a stationary wavelet transform(SWT) algorithm.In this paper, we discuss the ringing artifact suppression problem and analyze the characteristics of the deconvolution ringing artifact. The deconvolution data containing ringing artifacts are decomposed into different SWT subbands for analysis, and a new multiscale adaptive anisotropic filter is developed to suppress these degradations.Finally, we demonstrate the performance of the proposed method and describe the experiments in detail.
