The rapid development of computer vision algorithms increasingly allows automatic visual recognition to be incorporated into a suite of emerging applications. Some of these applications have less-than-ideal circumstances such as low-visibility environments, causing image captures to have degradations. In other more extreme applications, such as imagers for flexible wearables, smart clothing sensors, ultra-thin headset cameras, implantable in vivo imaging, and others, standard camera systems cannot even be deployed, requiring new types of imaging devices. Computational photography addresses the concerns above by designing new computational techniques and incorporating them into the image capture and formation pipeline. This raises a set of new questions. For example, what is the current state-of-the-art for image restoration for images captured in non-ideal circumstances? How can inference be performed on novel kinds of computational photography devices?

Continuing the success of the 1st (CVPR'18), 2nd (CVPR'19), 3rd (CVPR'20), 4th (CVPR'21), and 5th (CVPR'22) UG2 Prize Challenge workshops, we provide its 6th version for CVPR 2023. It will inherit the successful benchmark dataset, platform and evaluation tools used by the previous UG2 workshops, but will also look at brand new aspects of the overall problem, significantly augmenting its existing scope.
