Perceiving a discontinuity in motion.
Studies have shown that the position of a target stimulus is misperceived owing to ongoing motion. Although static forces (fixation, landmarks) affect perceived position, motion remains the overwhelming force driving estimates of position. Motion endpoint estimates biased in the direction of motion are perceptual signatures of motion's dominant role in localization. We sought conditions in whic...
متن کاملPerceiving object motion using vision and touch.
In a previous experiment, we showed that bistable visual object motion was partially disambiguated by tactile input. Here, we investigated this effect further by employing a more potent visuotactile stimulus. Monocular viewing of a tangible wire-frame sphere (TS) rotating about its vertical axis produced bistable alternations of direction. Touching the TS biased simultaneous and subsequent visu...
متن کاملRobust direct motion estimation considering discontinuity
In this paper, we propose a robust motion estimation algorithm using uncalibrated 3D motion model considering depth discontinuity. Most of the previous direct motion estimation algorithms with 3D motion model compute the depth value through the local smoothing, which result in erroneous results at depth discontinuity. In this paper, we overcome this problem at depth discontinuity by adding disc...

متن کاملPerceiving motion transparency in the absence of component direction differences
The simultaneous perception of multiple motion components within the same region in the visual field is a difficult processing task, which can be solved by human observers for a range of transparently moving stimuli. We use transparently moving gratings to study this phenomenon psychophysically, focussing on configurations in which individual components move in the same direction and can only b...
