Concise Radiometric Calibration Using The Power of Ranking

27 Jul 2017Han GongGraham D. FinlaysonMaryam M. Darrodi

Compared with raw images, the more common JPEG images are less useful for machine vision algorithms and professional photographers because JPEG-sRGB does not preserve a linear relation between pixel values and the light measured from the scene. A camera is said to be radiometrically calibrated if there is a computational model which can predict how the raw linear sensor image is mapped to the corresponding rendered image (e.g. JPEGs) and vice versa...
