Abstract: Abstract The Radon transform can sparsify the seismic data assuming that the events follow a certain type of trajectories. Commonly known Radon transforms include linear, parabolic, and hyperbolic transforms, which are usually exploited to process… read more here.

Abstract: ABSTRACTLeast-squares migration (LSM) can produce images with better balanced amplitudes and fewer artifacts than standard migration. The conventional objective function used for LSM minimizes the L2-norm of the data residual between the predicted and the… read more here.
