U-Nets analyzed as neural operators for inverse imaging problems

Researchers have explored U-Net architectures from a neural operator perspective to address inverse imaging problems. The study examines how these networks perform with increasing discretization resolution, a key factor in solving truly ill-posed problems. Experiments on limited-angle CT reconstruction suggest that while U-shaped neural operator architectures are inherently resolution-invariant, the traditional U-Net architecture demonstrates notable robustness to resolution changes.
