High quality black hole videos can provide key evidence of astrophysical processes that single static images cannot provide. However, reconstructing a video of a black hole is a highly ill-posed problem, requiring additional structural constraints to produce a plausible solution. Traditional structu…
We consider solving ill-posed imaging inverse problems without access to an explicit image prior or ground-truth examples. An overarching challenge in inverse problems is that there are many undesired images that fit to the observed measurements, thus requiring image priors to constrain the space of…
Typically, inversion algorithms assume that a forward model, which relates a source to its resulting measurements, is known and fixed. Using collected indirect measurements and the forward model, the goal becomes to recover the source. When the forward model is unknown, or imperfect, artifacts due t…
