CT Image Reconstruction from Sparse Projections Using Adaptive TpV Regularization

Figure 5

The MAE curves of reconstructed images with different reconstruction algorithms at 20 projection angles and different iteration numbers, and the iteration numbers range from 1 to 200. (a) The MAE curves of reconstructed images from noise-free projection data and (b) the curves of reconstructed images from noisy projection data.
