ICAM (Color Appearance Model)

iCAM is a color appearance model developed by Mark D. Fairchild and Garrett M. Johnson that was published in 2002 at the IS&T/SID 10th Color Imaging Conference in Scottsdale.^[1]

It has been recognized that there are significant aspects of color appearance phenomena that are not described well, if at all, by models such as CIECAM97s or CIECAM02.^[2]

The requirements for such a model include^[2]

Simple implementation for images
Spatially localized adaptation and tone mapping for high-dynamic-range images
Other spatial phenomena
Accurate color appearance
Scales for gamut mapping and other image editing procedures
Spatial filtering for visibility of artifacts
Color difference metrics for image quality assessment
