Efficient anti-aliasing and anti-leakage Fourier transform for high-dimensional seismic data regularization using cube removal and GPU
《Petroleum Science》2024年第5期3079-3089,共11页Lu Liu Sindi Ghada Fu-Hao Qin Youngseo Kim Vladimir Aleksic Hong-Wei Liu 
Seismic data is commonly acquired sparsely and irregularly, which necessitates the regularization of seismic data with anti-aliasing and anti-leakage methods during seismic data processing. We propose a novel method o...
