Two kinds of models have been proposed for taking into account the sensory processes at
work in the detection of visual motion: the feature model and the frequency-filter model. The …

Presents a model which assumes that visual detection of a motion depends on 2 separate
systems having different processing requirements. The movingness analyzing system (MAS) …

Several groups of authors have suggested separate mechanisms for the detection of motion
and for the detection of pattern characteristics of the same stimuli (Kulikowski, JJ and …

We studied the ability of human observers to detect abrupt changes in velocity of motion of a
random dot pattern. The pattern moved horizontally for 0.9 s at velocity V0, then changed to …

The direction of apparent motion in a complex pattern comprising a static 1-cycle/degree
(c/deg) grating and a moving 3-c/deg grating changes with stimulus duration. At durations …

Whether apparent motion occurs only between targets of similar spatial frequency was
examined. A “crossed phi” method was used, in which two potentially different targets …

An experimental paradigm is derived from a computational model of visual motion
perception. The new family of phenomena that support this paradigm is presented in the …

In the first part of this review a basic mechanism of motion perception was illustrated. The
elementary motion detector (EMD) of the correlation type can account for the detection of" …

Current “spatio-temporal energy” models of how we perceive pattern motion have been very
successful in helping us to understand the mechanisms of motion perception. Although they …

Human vision is effective at ambient light levels that vary from dim starlight (about 10-3
cd/m1.) to intense sunlight (about 105 cd/m1.). On the other hand, most visual phenomena …
