I recall seeing this applied years ago to astronomy images,
based on Bayesian logic. Given a low resolution image low,
find the high resolution image hi that maximizes

   p(hi) * p(low | hi)

Works well when hi consists of a lot of point sources like
stars. When used for crime, defining p(hi) is a great
opportunity for bias. Like, probably a male face since most
criminals are men.
