Fig. 8From: Efficient implementation of a local tomography reconstruction algorithmLine profiles of differences between reconstructions and ground truth. Blue difference between padded FBP \(x_0\) and ground truth \(x^\sharp\). Green difference between iterative total variation minimization \(\hat{x}\) and ground truth \(x^\sharp\). Left line profile, right column profile. Total Variation minimization removes both high- and low-frequency errors, exactly recovering the region of interestBack to article page
