The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Appearance modeling for tracking in multiple non-overlapping cameras (2005, methodology): “It is shown in [5] that most of the real world response functions are sufficiently well approximated by polynomials of degrees less than or equal to 10.”
Modeling inter-camera space-time and appearance relationships for tracking across non-overlapping views (2008, methodology): “Note that, a similar strategy was adopted by Grossberg and Nayar [9] to obtain a BTF between images taken from the same camera of the same view but in different illumination conditions.”
Deep High Dynamic Range Imaging with Large Foreground Motions (2017, methodology): “Given a stack of LDR images, if they are not in RAW format, we first linearize the images using the estimated inverse of Camera Response Function (CRF) [6], which is often referred to as radiometric calibration.”
