A Bayesian Hyperparameter Inference for Radon-Transformed Image Reconstruction

Figure 9

Qualities of reconstruction images measured by PSNR for real CT image reconstruction under the Gaussian noise. The horizontal axis shows the observation SD of Gaussian noise, and the vertical axis shows the PSNR. The solid line shows the result of our Bayesian method, and the dashed one shows that of the conventional FBP method.
