Goal
The aim of a demosaicing algorithm is to reconstruct a full color image (i.e. a full set of color triples) from the spatially undersampled color channels output from the CFA. The algorithm should have the following traits:
- Avoidance of the introduction of false color artifacts, such as chromatic aliases, zippering (abrupt unnatural changes of intensity over a number of neighboring pixels) and purple fringing
- Maximum preservation of the image resolution
- Low computational complexity for fast processing or efficient in-camera hardware implementation
- Amenability to analysis for accurate noise reduction

Famous quotes containing the word goal:
“What is done for science must also be done for art: accepting undesirable side effects for the sake of the main goal, and moreover diminishing their importance by making this main goal more magnificent. For one should reform forward, not backward: social illnesses, revolutions, are evolutions inhibited by a conserving stupidity.”
—Robert Musil (1880–1942)
“It will help us and our children if we can laugh at our faults. It will help us tolerate our shortcomings, and it will help our children see that the goal is to be a human, not perfect.”
—Neil Kurshan (20th century)
“When we have a great goal we are superior even to justice, not merely to our deeds and our judges.”
—Friedrich Nietzsche (1844–1900)
