iCAM is a Next-Generation 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.
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
Famous quotes containing the word appearance:
“Most lovers ... picture to themselves, in their mistresses, a secret reality, beyond and different from what they see every day. They are in love with somebody else—their own invention. And sometimes there is a secret reality; and sometimes reality and appearance are the same. The discovery, in either case, is likely to cause a shock.”
—Aldous Huxley (1894–1963)
