Video Acuity Measurement System

About this technology

Overview

Video systems are widely used in public safety and security applications, such as police, fire, emergency medical, commerce, and homeland security. There is an urgent need for a metric to quantify performance of video systems. The metric called video acuity, which is defined as the smallest letters, measured in units of visual angle, can be recognized when viewed through the video system. This automated system for measuring video acuity is based on a model of human letter recognition.
