Video Acuity: A Metric to Quantify the Effective Performance of Video Systems

Not Accessible

Your library or personal account may give you access

Abstract

There is a widely acknowledged need for metrics to quantify the performance of video systems. Existing metrics are either difficult to measure, or are largely theoretical, or do not reflect the full range of effects to which video may be subject, or do not relate easily to performance in real world tasks. We propose a new empirical metric –Video Acuity – that is simple to measure and is likely to relate directly to task performance. Video acuity is determined by the smallest letters that can be automatically identified through the video system. It is expressed most conveniently in letters per degree of visual angle. We provide examples of application of the metric to several video systems.
