We propose seismic elastic full-waveform inversion (EFWI) using both the multiparametric approximate Hessian and the discrete cosine transform (DCT). EFWI is a promising technology for obtaining ...

Full-waveform inversion (FWI) is a critical geophysical imaging technique, renowned for its ability to generate high-precision subsurface structural models. However, FWI is a highly nonlinear and ...
