NIIRS. Identify the wing configuration (e.g., straight, swept, delta) of all large aircraft (e.g., 707, CONCORD, BEAR, BLACKJACK). Identify radar and guidance areas at a SAM site by the configuration, mounds, and presence of concrete aprons. Detect a helipad by the configuration and markings.
These results indicate that the simplified GIQE can offer a useful tool for quick assessing image quality of various imaging systems. KEYWORDS: The National Imagery Interpretability Rating Scale (NIIRS), General Image Quality Equation (GIQE), Relative Edge Response (RER), Ground Sampling Distance (GSD), Signal to Noise Ratio (SNR).
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 assessing and communicating image quality and sensor system requirements.
The NIIRS was created to provide a user-friendly metric to define the image quality. It is a 10-level scale that helps analysts to assess quantitatively the quality of images for exploitation. The GIQE was developed specifically as a tool to estimate the NIIRS as a function of imaging system design parameters.
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
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.
