Through a process referred to as "rating" an image, the NIIRS is used by imagery analysts to assign a number which indicates the interpretability of a given image. The NIIRS concept provides a means to directly relate the quality of an image to the interpretation tasks for which it may be used.

21 lis 1997 · The NIIRS defines the levels of image interpretability by the types of tasks an analyst can perform with imagery of a given rating level. The NIIRS provides a simple, yet powerful, tool for...
This paper explores methods for quantifying image quality for automated image processing. In particular, we consider automated target detection (ATD) in gray-scale, electro-optical (EO)...
15 mar 2021 · In rating participants are asked to assign a single score to the image from a pre-defined scale. Rating results depend on the selection of images for the experiment and training procedure. At the same time, ranking is much simpler as it asks a simple question — which image is better.
20 lis 1997 · The NIIRS defines the levels of image interpretability by the types of tasks an analyst can perform with imagery of a given rating level. The NIIRS provides a simple, yet powerful, tool for assessing and communicating image quality and sensor system requirements.
2 maj 2018 · A typical measure of perceived image quality is known as the Mean Opinion Score (MOS). MOS is obtained by asking observers to rate images for their quality on a particular scale (such as a scale from 1 to 5 where 1 is bad and 5 is excellent).
These results indicate that the simplified GIQE can offer a useful tool for quick assessing image quality of various imaging systems.
