I thank Takeo Kanade for his insightful suggestions (especially on interpolation), and Branko
Jaramaz for introducing me to the metal artifact reduction problem. The NSF Advanced Compu-
tational Research program and the Heinz Endowment provided funding.
Abstract
Deferring discretization can occasionally change our perspective on imag-
ing problems. To illustrate, we offer a reformulation of regularized com-
puted tomography (CT) in which the large system of coupled equations for
the unknown smoothed image is decoupled into many smaller and simpler
