Fig. 7. Mean square difference between reconstructed volumes and ground truth volumes using the proposed wave kernel signature (WKS) graph descriptor, and the heat kernel signature (HKS) and random walk (RW) feature vector descriptors.

Fig. 7

For each method 250 values are generated, one for each timestep of the synthetic 4D volumes. Volumes are reconstructed using every sagittal slice and the median error taken, which is shown here. The proposed weighted MA scheme reduces the reconstruction errors in each case, and the WKS + weighted MA pipeline gives the lowest error.
