Neural image re-exposure

Images and videos often suffer from issues such as motion blur, video discontinuity, or rolling shutter artifacts. Prior studies typically focus on designing specific algorithms to address individual issues. In this paper, we highlight that these issues, albeit differently manifested, fundamentally stem from sub-optimal exposure processes. With this insight, we propose a paradigm termed re-exposure, which resolves the aforementioned issues by performing exposure simulation. Following this paradigm, we design a new architecture, which constructs visual content representation from images and event camera data, and performs exposure simulation in a controllable manner. Experiments demonstrate that, using only a single model, the proposed architecture can effectively address multiple visual issues, including motion blur, video discontinuity, and rolling shutter artifacts, even when these issues co-occur.
