[PDF] Nonuniformity Correction of Infrared Images by Midway

Non Uniformity Correction. 3. Top panel shows the correction of nonuniformity. From left to the The judgment mechanism of algorithm convergence is introduced and a smoothing function is designed to << eliminate ghosting >> Image uniformity and accurate radiometric calibration are key features of state-of-the-art infrared cameras

Thermal imaging sensors are sophisticated devices that require precise temperature readings For an internal NUC, the camera will cover the sensor with a shutter and use that shutter as a flat temperature.

Definition of s0 and s1 nonuniformity correction coefficients

Fluke TI Cameras automatically perform a NUC about every 60 seconds once turned on and stable Compared with other non-uniformity correction algorithms based on scene time-domain iteration, this algorithm can achieve non-uniformity correction under. The judgment mechanism of algorithm convergence is introduced and a smoothing function is designed to << eliminate ghosting >>

(PDF) Scene based nonuniformity correction in thermal images using. Image uniformity and accurate radiometric calibration are key features of state-of-the-art infrared cameras A non-uniformity correction (NUC) adjusts for those fluctuations by reading a flat, even scene and using that to calibrate all of the pixel readings for the same output

(PDF) Efficient single image nonuniformity correction algorithm. The correction algorithm based on a neural network is proposed Non-uniformity correction (NUC) adjusts for minor detector drift that occurs as the scene and environment change
