Figure 6 from An efficient nonuniformity correction technique for side

Non Uniformity Correction. Figure 2 from Adaptive Scenebased Nonuniformity Correction Method for For an internal NUC, the camera will cover the sensor with a shutter and use that shutter as a flat temperature. Thermal imaging sensors are sophisticated devices that require precise temperature readings

Although this is usually not necessary, it does allow you to force a NUC to occur without waiting for. To fully understand the importance of the NUC, see the link below or the attached .pdf

Nonuniformity Correction of Infrared Images by Midway Equalization

To improve accuracy, the camera measures the IR radiation from its own optics and then adjusts the image based on those readings Image uniformity and accurate radiometric calibration are key features of state-of-the-art infrared cameras Although this is usually not necessary, it does allow you to force a NUC to occur without waiting for.

Nonuniformity correction algorithm block diagram Download Scientific. Several techniques are reported in the literature to correct the image through NUC techniques It's possible to manually initiate a NUC even when the camera doesn't sense that it is necessary

Nonuniform correction effect diagram. (a) represent generated. For an internal NUC, the camera will cover the sensor with a shutter and use that shutter as a flat temperature. Hence, non uniformity correction includes both gain and offset correction
