Psychophysical evidence for a functional hierarchy of motion processing mechanisms.
Current models of motion perception typically describe mechanisms that operate locally to extract direction and speed information. To deal with the movement of self or objects with respect to the environment, higher-level receptive fields are presumably assembled from the outputs of such local analyzers. We find that the apparent speed of gratings viewed through four spatial apertures depends o...
متن کاملPsychophysical evidence against the autocorrelation theory of auditory temporal processing.
Nowadays, it is widely believed that the temporal structure of the auditory nerve fibers' response to sound stimuli plays an important role in auditory perception. An influential hypothesis is that information is extracted from this temporal structure by neural operations akin to an autocorrelation algorithm. The goal of the present work was to test this hypothesis. The stimuli consisted of seq...
متن کاملRobust structure from motion using motion parallax
We present an efficient and geometrically intuitive algorithm to reliably interpret the image velocities of moving objects in 3D. It is well known that under weak perspective the image motion of points on a plane can be characterised by an affine transformation. We show that the relative image motion of a nearby noncoplanar point and its projection on the plane is equivalent to motion parallax ...
متن کاملMotion parallax thresholds for unambiguous depth perception
The perception of unambiguous depth from motion parallax arises from the neural integration of retinal image motion and extra-retinal eye movement signals. It is only recently that these parameters have been articulated in the form of the motion/pursuit ratio. In the current study, we explored the lower limits of the parameter space in which observers could accurately perform near/far relative ...
