The term AI was coined in conjunction with the 1956 Summer AI Conference at Dartmouth College.
Historically, computer vision originated in AI.
Anecdote: In 1966, Marvin Minsky posed the development of a computer vision system as an undergraduate summer project. (The student, Gerald Sussman, did not stay in this domain.)
Computer vision emerged as its own discipline, particularly during the AI winter in the late 1980s.
First commercial success in the 1980s (machine vision); faster progress since the late 1990s.
Recently, connections to AI reappear (statistical techniques, machine learning, cognitive vision).
