Optimal transport distances have been recently proposed to design more convex misfit functions in the frame of full waveform inversion. The main difficulty for this strategy is the non-positivity of seismic data: the optimal transport is developed for the comparison of positive quantities. We review the proposed strategies to overcome this difficulty and put in light their limitations: in particular, those applicable to field data lose the convexity property. On this basis, we propose an… Expand
