Optic flow is the C
apparent motion of the landscape relative to the insect as it flies through it.
Optical flow (Horn and Schunck, 1981) is an estimation of the
apparent motion (velocity) of objects within an image sequence.
The perception of
apparent motion in music may involve the same neural mechanisms as motion perception in the visual domain.
The greater the
apparent motion, the nearer the star.
The cube itself, depending on the viewer's position in relation to it, may appear planar or volumetric, and seems to shift from stasis to
apparent motion. The twelve edges of each cube, literally framing the six panes, create a site where everything is suddenly intensified, the cube tethered by crisp lines that reinforce its geometric structure amid the amorphous atmospherics.
One alternative explanation is that the displacement pattern resulted from
apparent motion between the location of the launcher and the location of the target.
Our results showed that intermediate representation was not formed by mental rotation in depth rotation (the flipping strategy), however, Kourtzi and Shiffrar (1997, 1999a, 1999b) showed that the intermediate representation was formed by the
apparent motion of rotation in depth and plane.
This
apparent motion of the sky varies depending on where you are on the Earth--so latitude, or where you live is important.
MacKenzie and Bingham found that among their sample of 29 university students, 16 spontaneously adopted a strategy based on
apparent motion. Although there were no significant differences between the strategy users and nonusers on any IQ measure, the mean IT for the strategy users was found to be significantly shorter than that of the nonusers.
However, a potential limitation in current designs has been identified: the presence of ambiguous
apparent motion. Two theoretical explanations of ambiguous
apparent motion are discussed (Fourier and correspondence hypotheses).
The occurrence of
apparent motion both during and after body rotation has a long observational history (see Wade, 1998 a), but it was not subjected to experimental scrutiny until the late eighteenth century.
apparent motion - an optical illusion of motion produced by viewing a rapid succession of still pictures of a moving object; "the cinema relies on apparent motion"; "the succession of flashing lights gave an illusion of movement"
