Stability of Image-Reconstruction Algorithms

P. del Aguila Pla, S. Neumayer, M. Unser

IEEE Transactions on Computational Imaging, vol. 9, pp. 1-12, 2023.


Robustness and stability of image-reconstruction algorithms have recently come under scrutiny. Their importance to medical imaging cannot be overstated. We review the known results for the topical variational regularization strategies ( ℓ2 and ℓ1 regularization) and present novel stability results for ℓp-regularized linear inverse problems for p ∈ (1, ∞). Our results guarantee Lipschitz continuity for small p and Hölder continuity for larger p. They generalize well to the Lp(Ω) function spaces.
