Fig. 4

a Ground truth of synthetic CuO/CoO/Au nanocubes. b Nanocubes reconstructed with only Ψ2 (data consistency), λ1, λ3 = 0. The recovered tomograms are noisy. c Reconstructed with Ψ2 + TV, λ1 = 0. The expression Ψ2 + TV is equivalent to a denoising problem. d Reconstructed with Ψ1 and Ψ2 (model + data consistency), λ3 = 0. The tomograms remain noisy but structure has higher fidelity. e Reconstructed with MM-ET. Scale bar, 75 nm.
