This paper proposes a reflectivity constraint for velocity estimation to optimally solve the
inverse problem for active seismic imaging. This constraint is based on the velocity model …

Full-waveform inversion of seismic reflection data is highly nonlinear because of the
irregular form of the function measuring the misfit between the observed and the synthetic …

This thesis presents an acoustic migration/inversion algorithm that inverts seismic re flection
data for the angle dependent subsurface reflectivity by means of least-squares minimization …

We present an iterative non-linear inversion method to simultaneously estimate both velocity
and reflectivity. The core of the inversion workflow is a full acoustic wavefield modeling …

We present a combined imaging and velocity estimation scheme for seismic reflection data
that takes into account full wavefield propagation effects in complex subsurfaces. We aim at …

The inversion of seismic reflection data is challenging due to the oscillatory nature of the
seismic data, the nonlinear relation between the data and the Earth's model parameters, and …

We discuss the robustness of Joint Migration Inversion (JMI), which is a combined imaging
and velocity estimation scheme for seismic reflection data that takes into account primaries …

In seismic imaging, one tries to infer the medium properties of the subsurface from seismic
reflection data. These data are the result of an active source experiment, where an explosive …

We formulate the seismic inverse problem in an operator-based model-independent
approach where the model parameters, such as velocity and density in the acoustic …

Recorded seismic reflection waveforms contain information as to the small-scale variations
of impedance and the large-scale variations of velocity. This information can be retrieved by …
