DENOISING SEISMIC DATA |
| 摘要 |
Denoising seismic data can include extracting a first plurality of overlapping patches corresponding to a respective seismic data window selected from a plurality of seismic data windows, reshaping the first plurality of overlapping patches into patch vectors, and determining sparse approximations of the patch vectors based on a dictionary and a sparse coefficient vector. Denoising seismic data can also include reshaping the sparse approximations into a respective second plurality of overlapping patches, and constructing a denoised version of at least one of the plurality of seismic data windows using the respective second plurality overlapping patches. |

1. A method, comprising:
extracting a first plurality of overlapping patches corresponding to a respective seismic data window selected from a plurality of seismic data windows; reshaping the first plurality of overlapping patches into patch vectors; determining sparse approximations of the patch vectors based on a dictionary and a sparse coefficient vector; reshaping the sparse approximations into a respective second plurality of overlapping patches; and constructing a denoised version of at least one of the plurality of seismic data windows using the respective second plurality of overlapping patches. |
