Comparison of velocity profiles along 1-D sections. (a) Location of sampled 1-D sections. (b), (c) Velocity profile comparison when noise standard deviation was set to be σ = 10%|Vmax | at 1-D sections ‘1’ and ‘2’ respectively with resolution of 40 × 80 × 80 voxels. (d),(e) Velocity profile comparison when noise standard deviation was set to be σ = 50%|Vmax | at 1-D sections ‘1’ and ‘2’ respectively with resolution of 40 × 80 × 80 voxels. And (f),(g) Velocity profile comparison when noise standard deviation was set to be σ = 50%|Vmax | at 1-D sections ‘1’ and ‘2’ respectively with resolution of 21 × 51 × 25 voxels. Clearly, POD performs much better than all other methods. There is significant degradation in the results of other methods when noise level is increased.
