This paper explores the utility of visual acuity as a video quality metric for public safety applications. An
experiment has been conducted to track the relationship between visual acuity and the ability to perform a
forced-choice object recognition task with digital video of varying quality. Visual acuity is measured according
to the smallest letters reliably recognized on a reduced LogMAR chart.
