arXiv:2512.08444v2 Announce Type: replace-cross Abstract: Learned image reconstruction has become a pillar in computational imaging and inverse problems. Among the most successful approaches are learned iterative networks, which are formulated by unrolling classical iterative optimisation algorithms for solving variational problems. While the underlying algorithm is usually formulated in the functional analytic setting, learned approaches are often viewed as purely discrete. In this survey we present a unified operator view for learned iterative networks. Specifically, we formulate a learned r
The proliferation of AI in imaging applications necessitates more robust and theoretically grounded methods for reconstruction, pushing research towards unifying discrete and continuous approaches.
This development can lead to more reliable, interpretable, and generalizable AI models for image reconstruction, crucial for fields like medical imaging, remote sensing, and computational photography.
The theoretical understanding and methodological development of learned iterative networks shift from purely empirical discrete approaches to a more unified operator-theoretic framework, potentially improving performance and trustworthiness.
