Figure 7
Syntactic foam sample tomography acquired at ESRF ID19, with energy of 19 keV and pixel size of 0.28 µm. (a) Filtered back-projection. (b) Correction with RCP technique, using the parameters W = 60 and $[\theta_{0}]$ = 60. (c) Reconstruction with Total Variation technique, using the parameters $[\beta]$ = 0.35 and $[\beta_{r}]$ = 1×10^-6. (d) Reconstruction with Dictionary Learning technique, using the parameters $[\beta_{r}]$ = 0.1, $[\beta_{{\rm {DL}}}]$ = 0.035 and $[\rho]$ = 20.
