Interpolation in structure from motion.
We investigated surface interpolation in displays of structure from motion (SFM). To do so, we introduced a new method for measuring surface perception in dynamic displays--the SFM probe. An SFM probe is a dot that moves rigidly with the dots on a simulated surface, and whose distance from that surface can be adjusted with a joystick or similar control. The displays we studied were random-dot c...
متن کاملStructure-from-motion: Perceptual evidence for surface interpolation
Dynamic random-dot displays representing a rotating cylinder were used to investigate surface interpolation in the perception of structure-from-motion (SFM) in humans. Surface interpolation refers to a process in which a complete surface in depth is reconstructed from the object depth values extracted at the stimulus features. Surface interpolation will assign depth values even in parts of the ...
متن کاملMotion-surface labeling by orientation, spatial frequency and luminance polarity in 3-D structure-from-motion
A compelling percept of three-dimensionality is attainable from a purely motion-defined simulation of a transparent rotating cylinder, referred to as 3-D structure-from-motion (SFM). Interestingly, subjects rarely perceive reversals of the cylinder's direction of rotation when they are introduced. Treue, Andersen, Ando, and Hildreth (Vision Res. 35 (1995) 139-148) have argued that this reflects...
متن کاملTemporal integration in structure from motion.
A temporal integration model is proposed that predicts the results reported in 4 psychophysical experiments. The main findings were (a) the initial part of a structure-from-motion (SFM) sequence influences the orientation evoked by the final part of that sequence (an effect lasting for more than 1 s), and (b) for oscillating SFM sequences, perceived slant is affected by the oscillation frequenc...
متن کاملSpatial integration in structure from motion
In three experiments we investigated whether the perception of 3D structure from the optic-flow involves a process of spatial integration. The observer's task was to judge the 3D orientation of local velocity field patches. In two conditions, the patches were presented either in isolation, or as part of a global optic-flow. In Experiment 1, the global optic-flow was a linear velocity field. In ...
