Abstract

Human visual system is considered an imperfect communication channel, and there is investigated its ability to recognize quickly and correctly the various charts which are presented suddenly and randomly to an observer. Such ability is represented by the so-called informational efficiency of human vision. The fundamental equation of that quantity in the probability and binary form is derived, and also a suitable incoherent projection method for its measurement is described. Also some averaged and smoothed results of measurement of the informational efficiency in dependence on the time of chart presentation are shown for two sets of different 2D charts. Moreover, the method and the obtained results are evaluated.
