Figure 11
Profiles of difference between the reconstruction and the true interior for the Lena image. x₀, $[\hat{x}]$ and x^# are the padded FBP, the proposed reconstruction and the true interior, respectively. In blue: difference between the padded FBP and the true interior. In green: difference between the reconstruction with the proposed method with $[\sigma]$ = s = 3 and the true interior. First row: profiles of the middle line of the image for (a) R = 35, (b) no constraint ( R = 0). Second row: profiles of the middle column for (c) R = 35, (d) no constraint ( R = 0).
