Data reconstruction with abnormal and random noise and missing data. (a) Illustration of original data slices within the CMP domain (⁠|$CMPx = 8,\textit{CMPy} = 8,Hy = 2,5,8,10$|⁠); (b) input data contaminated with −1 dB random noise, 20% of seismic traces affected by abnormal noise, and 30% of seismic traces randomly missing; (c) reconstruction result using the FN-TC method, with SNR = 23.4 dB; and (d) error analysis between the reconstruction (c) and the original data (a).
