WebJul 1, 2015 · In recent years, many studies have been performed to reconstruct traces missing from irregularly undersampled seismic data. In this paper, we introduce a new curvelet-transform-based projection onto convex sets (POCS) algorithm that applies the curvelet transform to 2D Fourier-transformed data in the f–k domain instead of data in … WebDec 13, 2024 · For each iteration, we use the DL framework to denoise the 3D seismic data and initially reconstruct the missing traces. Then, the projection onto convex sets (POCS) algorithm is used for further enhancement of the seismic data reconstruction. The output of the POCS is considered as the input for the DL network in the next iteration. 4301 largo street farmington nm WebSeismic trace interpolation is necessary for high-resolution imaging when the acquired data are not adequate or when some traces are missing.
