Wertheimer's pure phi phenomenon and beta movement are often confused in explanations of film and animation, [6] [8] but they are quite different perceptually and neither really explains the short-range apparent motion seen in film. [1] In beta movement, two stimuli, and , appear in succession, but are perceived as the motion of a single object ...
Although this process appears straightforward to most observers, it has proven to be a difficult problem from a computational perspective, and difficult to explain in terms of neural processing. Motion perception is studied by many disciplines, including psychology (i.e. visual perception), neurology, neurophysiology, engineering, and computer ...
The term phi phenomenon is used in a narrow sense for an apparent motion that is observed if two nearby optical stimuli are presented in alternation with a relatively high frequency. In contrast to beta movement, seen at lower frequencies, the stimuli themselves do not appear to move. Instead, a diffuse, amorphous shadowlike something seems to ...
Beta movement, an illusion of movement where two or more still images are combined by the brain into surmised motion; Illusory motion, the appearance of movement in a static image; Phi phenomenon, an illusion of movement created when two or more adjacent lights blink on and off in succession

Billboards and other electronic signs use apparent motion to simulate moving text by flashing lights on and off as if the text is moving.. The term illusory motion, or motion illusion or apparent motion, refers to any optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color contrasts, object shapes, and position.

Using beta to evaluate a stock’s risk. Beta allows for a good comparison between an individual stock and a market-tracking index fund, but it doesn’t offer a complete portrait of a stock’s ...
