The prodigious spatial capabilities of the primate visual system are even more remarkable when temporal considerations are taken into account. Recent advances in neurophysiology, psychophysics and computer vision provide significant constraints on how the system could work. This paper presents a fairly detailed connectionist computational model of how the perception and recognition of objects is carried out by primate brains. The model is claimed to be functionally adequate and to satisfy all the constraints established by the various disciplines. One key notion introduced is a multi-input, multi-output network for inverting spatio-temporal cues. The central construct in intermediate level motion vision is taken to be the trajectory and these are used in recognition of dynamic situations called scenarios. The entire development is an extension of the author's 1985 Four Frames model, which required relatively little modification to accommodate temporal change (eventually).
