The National Imagery Interpretability Scale (NIIRS) promotes interoperability for the exchange of data among Intelligence, Surveillance, and Reconnaissance (ISR) Systems. The scales allow for the evaluation of imagery quality and use of a consistent measure for such evaluations.
21 lis 1997 · The NIIRS provides a simple, yet powerful, tool for assessing and communicating image quality and sensor system requirements. While the scale itself is simple, the process of developing the...
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. Military and Civil NIIRS scales are used to grade visible, radar, infra-red and multispectral imagery.
For exploitation of imagery by an analyst, the National Imagery Interpretability Rating Scale (NIIRS) provides a standard measure. The NIIRS is a quantification of image interpretability that...
The NIIRS consists of 10 levels, from 0 (worst quality) to 9 (best quality). Because different types of imagery support different types of interpretation tasks, individual NIIRS has been developed for four major imaging types: Visible, Radar, Infrared, and Multispectral.
21 lis 1997 · A regression-based model was developed relating aerial image quality, expressed in terms of the National Imagery Interpretability Rating Scale (NIIRS), to fundamental image attributes, and allows system designers and operators to perform trade-offs for the optimization of image quality.
