NIIRS is a subjective scale that defines different levels of image quality/interpretability for various types of imaging systems. It has 10 levels, from 0 (worst) to 9 (best), and is published by the Federation of American Scientists.
NIIRS stands for National Image Interpretability Rating Scale, a system to measure the quality and interpretability of aerial imagery. It assigns a number from 1 to 9 based on the ability to detect and identify features at different scales and resolutions.
21 lis 1997 · Jitter-induced degradation is evaluated in terms of the National Imagery Interpretability Rating Scale (NIIRS), which is measured in terms of the general image quality equation (GIQE).
The National Imagery Interpretability Rating Scale (NIIRS) is used by imagery analysts to define the quality of aerial imagery from different imaging systems. The scale uses a number to indicate the level of detail which may be seen in an image, and therefore how much information may be expected from it.
This document presents the Civil National Imagery Interpretability Rating Scale (NIIRS) and discusses its use. Image examples using the Civil NIIRS are displayed in Appendix I. Additional Civil NIIRS criteria are listed in Appendix II and a history of NIIRS appears in Appendix III.
