Fast Gabor imaging with spatial resampling

Yongwang Ma and Gary F. Margrave

ABSTRACT

Gabor depth imaging method has been made much more efficient thanks to adaptive partitioning algorithms. Moreover, as introduced in another space-frequency domain imaging method, called the forward operator and conjugate inverse, wavefield extrapolation operator lengths at low frequencies can be decreased, resulting in a lower computation cost. This is known as the spatial resampling technique, which can be implemented in the Gabor imaging method because this imaging method works in the space-frequency domain, too. In this paper, we demonstrate the application of spatial resampling in the Gabor imaging method, which will substantially improve the imaging speed.
