Color appearance models

ICAM (color appearance model)

iCAM, short for image color appearance model, is developed by and and initially published in 2002 at the IS&T/SID 10th Color Imaging Conference in Scottsdale, Arizona. As of May 2019, the latest version appears to be iCAM06, a 2006 revision that expanded tone mapping capacities for HDR. 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. The requirements for such a model include: * 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 As of 2013, iCAM06 is capable of reaching all of the goals above. Temporal effects have been noted as a future direction of development according to Fairchild's lecture slides. (Wikipedia).
