Based on the mathematical and physical theory of wave equation, the full waveform inversion, travel-time tomography, least squares migration and migration velocity analysis can be included into a same inversion frame. Based on Bayes theory, this paper analyzed and compared these methods. It is proved that the full waveform inversion can use most seismic information, but the overlying of different information increases the difficulty of its usage. Under the guidance of signature waveform inversion, the characterized information were extracted to carry out seismic inversion, and several schemes were analyzed and compared theoretically.
