Denoising of the stack of projections of 00072. Top-to-bottom: display of a single sinogram of the noisy stack of projections Z (4)[link], the corresponding estimate of the underlying projections [\widehat{\ln(A)}] from the proposed procedure, and the corresponding tomograms of Z and the estimates [\hat{Y}] of streak-free stacks Y (5)[link], respectively, obtained with filtered back-projection. The tomogram for [\widehat{\ln(A)}] is shown in Fig. 11[link]. Although the data present challenges through inconsistent noise intensities across the angular dimension, most streak noise and Poissonian noise is attenuated without notable loss of signal.
