Vision tasks with constrained camera motion have been discussed for a long time since Active Vision appeared. As an example, Camera under planar motion can often simplify the works, like camera self-calibration, scene reconstruction and robot self-location. In this paper, we provide detail information on the algebraic characteristic and geometric interpretation of planar motion. It does help to...

The perceived speed of motion in depth (MID) for a monocularly visible target was measured in central and peripheral vision using a 2AFC speed discrimination task. Only binocular cues to MID were available: changing disparity and interocular velocity difference (IOVD). Perceived speed for monocular lateral motion and perceived depth for static disparity were also assessed, again in both central...

Neural processing of 2D visual motion has been studied extensively, but relatively little is known about how visual cortical neurons represent visual motion trajectories that include a component toward or away from the observer (motion in depth). Psychophysical studies have demonstrated that humans perceive motion in depth based on both changes in binocular disparity over time (CD cue) and inte...
