Use in Computer Image Processing Software
When one has access to the raw image data from a digital camera, one can use computer software with a variety of different demosaicing algorithms instead of being limited to the one built into the camera. A few raw development programs, such as RawTherapee, give the user an option to choose which algorithm should be used. Most programs, however, are coded to use one particular method. The differences in rendering the finest detail (and grain texture) that come from the choice of demosaicing algorithm are among the main differences between various raw developers; often photographers will prefer a particular program for aesthetic reasons related to this effect.
The color artifacts due to demosaicing provide important clues for identifying photo forgeries.

Famous quotes containing the words computer and/or image:
“What, then, is the basic difference between today’s computer and an intelligent being? It is that the computer can be made to see but not to perceive. What matters here is not that the computer is without consciousness but that thus far it is incapable of the spontaneous grasp of pattern—a capacity essential to perception and intelligence.”
—Rudolf Arnheim (b. 1904)
“The whole world is an omen and a sign. Why look so wistfully in a corner? Man is the Image of God. Why run after a ghost or a dream? The voice of divination resounds everywhere and runs to waste unheard, unregarded, as the mountains echo with the bleatings of cattle.”
—Ralph Waldo Emerson (1803–1882)
