AUTOCORRELATION FUNCTION AND BINOCULAR BRIGHTNESS MIXING

In this investigation a theoretical model of binocular brightness mixing is tested. According to the model, the brightness of the binocular combination of any pair of monocular brightnesses is equal to the vector sum of the monocular brightnesses, each monocular brightness being weighted in proportion to the contour and contrast properties of the monocular stimulus. The monocular weightings are derived from a special autocorrelation function which provides a measure of contour and contrast. The model successfully reproduces, by means of computer simulation, the data of six previously published experiments on binocular brightness mixing (Fry and Bartley, 1933; Levelt, 1965). In addition it is demonstrated that the autocorrelation function has potential application to other, more general, problems of pattern perception. © 1969.
