Fig. 6

Recovery of the estimated average velocities by changing the size of the velocity jump: a 0.0 km/s; b 0.2 km/s; and c 0.5 km/s. d MAE variations for each of the tested velocity jumps and methods (DLS, \({l}_{2}\)-smoothness regularization (L2), and the proposed methods). Colored lines in a–c are the same as those in Fig. 4
