Figure 8.

Reconstruction from noisy projections. There are six figures displaying the reconstruction results from noisy projections. The projections in different figures are corrupted by the noise to different extent. The SNR underneath each figure indicates the signal noise ratio. We can conclude, from the observation and comparison of the six reconstructed images, that our method is tolerable to noisy data. The reconstruction quality seems reasonable even when the SNR is around 2 dB, in Figure (B).
