iCAM (color appearance model)
iCAM, short for image color appearance model, is developed by Mark D. Fairchild and Garrett M. Johnson and initially published in 2002 at the IS&T/SID 10th Color Imaging Conference in Scottsdale, Arizona.[1] As of May 2019[update], the latest version appears to be iCAM06, a 2006 revision that expanded tone mapping capacities for HDR.[2]
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.[3]
The requirements for such a model include:[3]
- 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.[4]
