Software to Stress Test Image Quality Estimators

An image quality estimator (QE) can be used to improve the performance of a system, but only if its scores are easily interpretable. In this paper, we present software, entitled “Stress Testing Image Quality Estimators (STIQE)” that systematically explores the performance of a QE, with the goal of enabling users to interpret the QE's scores. Our software allows consistent and reproducible benchmarks of new QEs as they are developed, so the most effective QE for an application can be chosen. We demonstrate that results produced by the software provide new insights into hidden aspects of existing QEs.
