Fast least-squares migration with a deblurring filter (2009, neutral): “…(Hu et al., 2001; Etgen, 2002; Guitton, 2004; Yu et al., 2006; Lecomte, 2008; Toxopeus et al., 2008), or a least squares migration (LSM) scheme can be implemented (Nemeth et al., 1999; Chavent and Plessix, 1999; Duijndam et al., 2000; Kuhl and Sacchi, 2003; Plessix and Mulder, 2004; Symes, 2008).”
A parametrization study for surface seismic full waveform inversion in an acoustic vertical transversely isotropic medium (2011, methodology): “The diagonal values are the inverse of the Born approximation of the Hessian computed in a constant medium (Plessix & Mulder 2004).”
Sparsity- and continuity-promoting seismic image recovery with curvelet frames (2008, methodology): “These scaling methods either calculate the weighting analytically [36,45], based on certain assumptions regarding the acquisition and velocity model, or estimate the diagonal weighting from the action of the normal operator on some reference vector, an idea first suggest by Symes and reported in [17”
Q-compensated least-squares reverse time migration using low-rank one-step wave extrapolation (2016, methodology): “The square matrix A∗A is known as the wave-equation Hessian, and its condition number affects the convergence rate of LSRTM implemented as an iterative inversion (Plessix and Mulder, 2004).”
Regularized seismic full waveform inversion with prior model information (2013, background): “In such a configuration with a small offset compared to the depth, the FWI behaves generally like a non-linear migration technique, as the low part of the wavenumber domain can not be retrieved (Plessix and Mulder, 2004) and we may question how the prior information may fill in this part of wavenumb”
