A study on correlation between national imagery interpretability rating scale and discrimination probability

Abstract

The status quo of performance evaluation method for optical imaging system in our country is introduced in the article. At the same time, the definitions and applied fields for discrimination probability，National Imagery Interpretability Rating Scale（NIIRS）and General Image Quality Equation (GIQE) are introduced, too. Under ideal conditions, utilizing ground resolution distance the dependence model between NIIRS and discrimination probability is established. Utilizing this model, we can solve the difficulties of optical imaging system performance evaluation using these two different evaluation methods.
