...Mostafa Naghizadeh; Mauricio Sacchi ABSTRACT We tested a strategy for beyond-alias interpolation of seismic data using Cadzow reconstruction. The strategy enables Cadzow reconstruction to be used for interpolation of regularly sampled seismic records. First, in the frequency-space ( f - x ) domain...

...Jianjun Gao; Mauricio D. Sacchi; Xiaohong Chen ABSTRACT Rank reduction strategies can be employed to attenuate noise and for prestack seismic data regularization. We present a fast version of Cadzow reduced-rank reconstruction method. Cadzow reconstruction is implemented by embedding 4D spatial...

... usually perform well with irregularly missing traces but they are inappropriate for the reconstruction of regularly sampled seismic data. To reconstruct seismic data with regularly missing traces, Naghizadeh and Sacchi (2013) propose the dealiased Cadzow method. With the development of machine...

..., 1986 ; Van Loan, 1992 ), recently proposed by Korobeynikov (2010) and used for seismic data filtering and reconstruction purposes by Trickett (2003) and Gao et al. (2013) . This article is organized as follows: First, we expose the motivation behind the Cadzow/SSA signal model; second, we...

...) and Oropeza and Sacchi (2011) is equivalent to the Cadzow method proposed by Trickett (2008) for denoising and reconstructing seismic volumes. Cadzow and MSSA algorithms replace the block Hankel matrix of the incomplete and noisy multidimensional observations by its low-rank approximation. Averaging along...

...Figure 11. Local comparisons for different reconstruction results: (a) enlargement of incomplete field DAS-VSP data and (b–g) reconstruction results of f - x deconvolution, CS-OMP, Cadzow filtering, DnCNN, U-Net, and MCA-Net, respectively. ...

... ( Trickett, 2002 , 2008 ) and multichannel singular spectrum analysis ( Oropeza and Sacchi, 2011 ). Cadzow filtering can reconstruct several linear events with different slopes at the same time; however, it produces noticeable artifacts for isolated large-amplitude noise (erratic noise) and blurs...

... removed the sticky coherent noise by a local pseudo f - x - y Cadzow filtering. Then, we diminished the random noise by a structure-oriented filtering. Finally, we extended the frequency bandwidth with a spectral-balancing method based on the continuous wavelet transform. The data quality was improved...
