The Free On-line Dictionary of Computing (30 December 2018):

computer vision

    A branch of artificial intelligence and image
   processing concerned with computer processing of images from the
   real world.  Computer vision typically requires a combination of
   low level image processing to enhance the image quality
   (e.g. remove noise, increase contrast), pattern recognition to
   recognise features such as lines, areas and colours and image
   understanding to translate these features into knowledge about
   the objects in the scene.
