Deblending comparison for numerically blended synthetic data (complex gather). (a) Deblended result using
domain thresholding. (b) Deblended result using seislet-domain thresholding. (c) Deblended result using
predictive filtering. (d) Blending noise corresponding to (a). (e) Blending noise corresponding to (b). (f) Blending noise corresponding to (c). (g) Estimation error corresponding to (a). (h) Estimation error corresponding to (b). (i) Estimation error corresponding to (c).

Diagrams of SNR for synthetic example (complex gather). The "+" line corresponds to seislet-domain thresholding. The "o" line corresponds to
domain thresholding. The "*" line corresponds to
predictive filtering.
