Visual Communication - Visual Communication Channel

Visual Communication Channel

The information theory of visual communication encompasses:

  1. Image gathering, to capture the radiance field that is either reflected or emitted by the scene and transform this field into a digital signal.

  2. Signal coding, to encode the acquired signal for the efficient transmission and/or storage of data and decode the received signal for the restoration of images.

  3. Image restoration, to produce a digital representation of the scene and transform this representation into a continuous image for the observer.

  4. Human vision, to assess image systems in terms of the information rate that the eye of the observer conveys from the displayed image to the higher levels of the brain.
