A Bayesian Hyperparameter Inference for Radon-Transformed Image Reconstruction

Figure 4

Reconstruction performance against hyperparameter 𝛽. The horizontal axis shows the 𝛽, and the vertical one shows the PSNR. Other hyperparameters, ℎ and 𝛾, are fixed to the estimated value. The filled rectangle shows the result of our hyperparameter inference for 𝛽.
