Abstract
Energy-based motion detection models have been used as a model of the Fourier motion detection mechanism in human vision. However, conditions to guarantee the models' validity are not necessarily clarified. In this paper, we evaluate the energy models' performance in reproducing reverse motion perception(motion illusion)and Fourier mechanism's disruption for two-frame and multi-frame apparent motion, respectively, and find appropriate conditions. It is shown that two kinds of energy models' temporal filters should be Hilbert transforms of each other and that the filters' band-width should be as broad as the visual filter's. Computationally, these results suggest that there also exists a temporal Hilbert filter in the Fourier mechanism and that the broad band-width of the visual temporal filters is reasonable. Moreover, the optimized energy model gives an interpretation to the disruption mechanism.
