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.
We wanted to freeze the apparent motion
of the bullet, so we chose the shortest integration time (shutter speed) for this camera, which is 10 [micro]sec.
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.
