ABSTRACT
The study of linguistic and visual perceptions has been undertaken by several pioneering authors such as H. Blum [3] in 1967, D. Marr and E. Hildreth [20] in 1980 and D. Marr [21] in 1982. It involves specialists in psychology, artificial intelligence, and experimentalists such as Hubel and Wiesel [16] in 1962 and Campbell and Robson [6] in 1968.
