  • Ringing
  • Contouring
  • Posterizing
  • Staircase noise (aliasing) along curving edges
  • Blockiness in "busy" regions (sometimes called quilting or checkerboarding)

Famous quotes containing the word images:

    “Wisdom and Spirit of the universe!
    Thou Soul that art the eternity of thought,
    That givest to forms and images a breath
    And everlasting motion,”
    —William Wordsworth (1770–1850)

    “No healthy man, in his secret heart, is content with his destiny. He is tortured by dreams and images as a child is tortured by the thought of a state of existence in which it would live in a candy store and have two stomachs.”
    —H.L. (Henry Lewis)

    “Isn’t life a series of images that change as they repeat themselves?”
    —Andy Warhol (c. 1928–1987)
