Missing trace reconstruction is a challenge in seismic processing due to incomplete and irregular acquisition. Noise is a concern, due to the many sources of noise that occur during seismic acquisition. Most of the recent research on denoising and interpolation focuses on transform domain approaches using L1 norm minimization. A specific kind of constraint, called the synthesis approach, is wid...
Lock acquisition of a suspended optical cavity can be a highly stochastic process and is therefore nontrivial. Guided lock is a method to make lock acquisition less stochastic by decelerating the motion of the cavity length based on an extrapolation of the motion from an instantaneous velocity measurement. We propose an improved scheme that is less susceptible to seismic disturbances by incorpo...
Towed streamer operations in congested areas lead to gaps in 3D coverage making the OBC (Ocean Bottom Cable) method employing detectors on the ocean bottom a necessity. In order to ensure that high quality seismic data is obtained using this method one has to address the problem of water column reverberation at the acquisition stage itself. Every primary arrival at a detector location is follow...
