Blind face restoration is a highly ill-posed problem that often requires
auxiliary guidance to 1) improve the mapping from degraded inputs to desired
outputs, or 2) complement high-quality details lost in the inputs. In this
paper, we demonstrate that a learned discrete codebook prior in a small proxy
space largely reduces the uncertainty and ambiguity of restoration mapping by
casting blind face restoration as a code prediction task, while providing rich
visual atoms for generating high-quality faces. Under this paradigm, …
