For example, Barclay et al. [12], and Kozlowski and Cutting [13] showed
that humans can recognize the gender of a walker from an MLD. However, for
short exposures to the MLD (two seconds or less), humans were no better than
random. It required longer exposures, on the order of four seconds, for humans
to perform better than random. Even at that, the recognition rate was 66% when
random was 50%.
