- Ringing
- Contouring
- Posterizing
- Staircase noise (aliasing) along curving edges

Famous quotes containing the word images:
“I tell it stories now and then
and feed it images like honey.
I will not speculate today
with poems that think they’re money.”
—Anne Sexton (1928–1974)
“The romance and mystery is [sic] gone. Computer-processed images have no delicacy, no craftsmanship, no substance, and no soul. No love.”
—Kim Nibblett (b. c. 1969)
“It is not the literal past that rules us, save, possibly, in a biological sense. It is images of the past.... Each new historical era mirrors itself in the picture and active mythology of its past or of a past borrowed from other cultures. It tests its sense of identity, of regress or new achievement against that past.”
—George Steiner (b. 1929)
