Parallel model of the kinetic depth effect using local computations.
This paper defines a new model for the kinetic depth effect for multidot stimuli. The calculation is performed in a cooperative-competitive network, described as a relaxation labeling process. The process involves a local iterative computation to meet best the constraints indicated by image cues to depth. Given a constraint that prefers interdot distances in three dimensions to remain constant (local rigidity), the model becomes a local parallel computation of the Ullman incremental-rigidity scheme. Several simulations of the model are described, including some in which additional cues are combined with the changing-dot-position cue.
