Illusory contours or subjective contours are visual illusions that evoke the perception of an edge without a luminance or color change across that edge. Illusory brightness and depth ordering frequently accompany illusory contours. Friedrich Schumann is often credited with the discovery of illusory contours around the beginning of the twentieth century, [1] however illusory contours are present in art dating to the Middle Ages. Gaetano Kanizsa's 1976 Scientific American paper marks the resurgence of interest in illusory contours for vision scientists.
