## An efficient numerical method for the solution of the $$L_2$$ optimal mass transfer problem.(English)Zbl 1428.49034

Summary: In this paper, we present a new computationally efficient numerical scheme for the minimizing flow approach for the computation of the optimal $$L_2$$ mass transport mapping. In contrast to the integration of a time dependent partial differential equation proposed in [S. Angenent et al., SIAM J. Math. Anal. 35, No. 1, 61–97 (2003; Zbl 1042.49040)], we employ in the present work a direct variational method. The efficacy of the approach is demonstrated on both real and synthetic data.
