Table 1. For two SNR values, the results are shown for the DTI method described in Section 3.2, with or without nonlinear enhancements.
We compare with CSD and a specific instance of enhanced CSD with parameters D 33 = 1, D 44 = 0.01,t = 2. For local metric θ lower is better, for the other metrics higher is better. In boldface are the best results for the DTI and CSD methods.
