On cycle-skipping and misfit function modification for full-wave inversion: Comparison of five recent approaches

Full-waveform inversion, a high-resolution seismic imaging method, is known to require sufficiently accurate initial models converge toward meaningful estimations of the subsurface mechanical properties. This limitation due nonconvexity least-squares distance with respect kinematic mismatch. We propose comparison five misfit functions promoted recently mitigate this issue: adaptive waveform instantaneous envelope, normalized integration, and two methods based on optimal transport. explain which principles these are illustrate how they designed better handle mismatch than function. By doing so, we can exhibit specific limitations in canonical cases. further assess interest approaches for application field data synthetic Marmousi case study. inversion transport possess interesting properties, making them appealing strategies applicable data. Another outcome definition generic tools compare full-waveform inversion.
