We present an application of deep generative models in the context of partial differential
equation constrained inverse problems. We combine a generative adversarial network …

早期地震偏移的目标是通过寻找地下反射面的位置来落实井位. 经过半个多世纪的发展,
地震偏移技术日趋精深. 特别是随着叠前深度偏移的广泛应用, 地震偏移结果为解释人员进行 …

This work presents the first quantitative ultrasonic sound speed images of ex vivo limb cross-
sections containing both soft tissue and bone using Full Waveform Inversion (FWI) with level …

When present in the subsurface, salt bodies impact the complexity of wave-equation-based
seismic imaging techniques, such as least-squares reverse time migration and full-waveform …

The need to improve the depth resolution of the magnetic susceptibility model recovered
from surface magnetic data is a well-known challenge, and it becomes increasingly …

In this paper, the acoustic inverse problem modeled in the time domain featuring wave
velocity reconstruction in the presence of sharp interfaces is addressed using an integer …

A level set based shape evolution approach is presented for the inversion of elastic
waveform data with a special emphasis on the application to seismic full waveform …

In this paper, a comparison of stochastic optimization algorithms is presented for the
reconstruction of electromagnetic profiles in through-the-wall radar imaging. We combine …

This thesis is dedicated to the study of methods for the initialization of seismic full-waveform
inversion. Full-waveform inversion (FWI) is a non-linear optimization technique for high …

Two long-standing challenges for geophysical inverse problems are nonuniqueness
(especially in the multiparameter setting) and the slow convergence of gradient-based …
