Abstract

Quality assessment is a key element for the evaluation of hardware and software involved inimage and video acquisition, processing, and visualization. In the medical field, user-basedquality assessment is still considered more reliable than objective methods, which allow theimplementation of automated and more efficient solutions. Regardless of increasing researchon this topic in the last decade, defining quality standards for medical content remains a nontrivial task, as the focus should be on the diagnostic value assessed by expert viewers ratherthan the perceived quality from naïve viewers, and objective quality metrics should aim atestimating the first rather than the latter. In this paper, we present a survey of methodologiesused for the objective quality assessment of medical images and videos, dividing them intovisual quality-based and task-based approaches. Visual quality-based methods compute aquality index directly from visual attributes, while task-based methods, being increasinglyexplored, measure the impact of quality impairments on the performance of a specific task. Adiscussion on the limitations of state-of-the-art research on this topic is also provided, alongwith future challenges to be addressed.
