Abstract/OtherAbstract:
Spatio-temporal interpolation creates the impression of motion from a rapid sequence of stationary images by reconstructing the motion path in between the stations actually presented. Thresholds below the diameter of foveal photoreceptors have been obtained with two-dimensional spatio-temporal interpolation. We found that also three-dimensional interpolation, i.e. interpolation in depth, where information from motion detectors tuned to opposite directions in both eyes has to be combined, yields thresholds in the hyperacuity range. The results of parametric experiments favour the interpretation that interpolation occurs at a monocular stage of visual processing, rather than on a stereoscopic stage.
