Popis:	Initializing the Full Waveform Inversion (FWI) iterations from sufficiently low frequencies through a multiscale scheme provides long wavelength information in the early stages of FWI and yields the convergence to the correct solution of the problem. However, because of the band-limited nature of the acquired seismic data the low frequency components are not practically observed and it is not realistic to start the FWI from frequencies lower than recording limits (
