  A broad class of problems at the core of computational imaging, sensing, and
low-level computer vision reduces to the inverse problem of extracting latent
images that follow a prior distribution, from measurements taken under a known
physical image formation model. Traditionally, hand-crafted priors along with
iterative optimization methods have been used to solve such problems. In this
paper we present unrolled optimization with deep priors, a principled framework
for infusing knowledge of the image formation into deep networks that solve
inverse problems in imaging, inspired by classical iterative methods. We show
that instances of the framework outperform the state-of-the-art by a
substantial margin for a wide variety of imaging problems, such as denoising,
deblurring, and compressed sensing magnetic resonance imaging (MRI). Moreover,
we conduct experiments that explain how the framework is best used and why it
outperforms previous methods.
