Table 1

Comparison of -norm errors for the velocity field recovered by the proposed reconstruction model and synthetic velocity field. The first and second columns represent normalized pointwise error of velocity and vorticity in , respectively. The third and fourth columns represent normalized -norm in global energy estimates of velocity and vorticity, respectively. Here, , , ,  , and . Note that the superscripts and denote the forward and reconstructed data, respectively.
