We studied whether the cooperative motion detection model is effective in reproducing human vision's motion detection and accommodation characteristics for many kinds of apparent motion stimuli. The stimuli consisted of two kinds of apparent motion sine-waves with different motion directions, and the model's responses to the stimuli were compared with actual responses in human vision. The responses corresponded well in two ways. (1) There was a critical spatial frequency at which the motion perception changed from one state to the other, and it increased as the stimuli approached in a continuous motion. (2) Under the critical spatial frequency, two kinds of motion were detected in two kinds of accommodation states depending on which motion stimulus was paid attention to, while over the critical frequency, one motion was detected in those states. These results suggest that the cooperative model is an accurate model of the motion detection mechanism including the accommodation mechanism.
