Visual acuity and task-based video quality in public safety applications
Joel M. Dumke · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2013
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.
