Stereopsis, spatial frequency and retinal eccentricity
Stereoscopic depth discrimination thresholds increase with retinal eccentricity and distance from the horopter. However, in contrast to spatial resolution, the effects of spatial frequency on stereo-thresholds in the periphery are unknown. For spatial vision, it is generally assumed that the retina is comprised of a series of overlapping spatial filter mechanisms and that there is a commensurat...
متن کاملSpatial-frequency and contrast tuning of the transient-stereopsis system
The tuning of the transient-stereopsis system to luminance contrast and spatial-frequency (SF) was investigated with narrow-band gabor targets with a constant sigma of 1 degree. They were presented for brief (140 ms) durations and subtended a large (6 degrees) disparity. When dichoptic gabor stimuli were matched in SF (0-5 cpd), transient stereo performance was either uniform across SF or great...
متن کاملA Spatiotemporal/Spatiotemporal-Frequency Interpretation of Apparent Motion Reversal
Temporal aliasing artifacts are common in both computer generated and natural motion sequences. One of the most striking manifestations of temporal aliasing is the apparent reversal of motion commonly referred to as the "wagon wheel effect." In this paper, we examine temporal aliasing from the standpoint of joint spatiotemporal/spatiotemporal-frequency representations. We show that apparent mot...

15 صفحه اولContrast masking reveals spatial-frequency channels in stereopsis.
Yang and Blake (1991 Vision Research 31 1177-1189) investigated depth detection in stereograms containing spatially narrow-band signal and noise energies. The resulting masking functions led them to conclude that stereo vision was subserved by only two channels peaking at 3 and 5 cycles deg-1. Glennerster and Parker (1997 Vision Research 37 2143-2152) re-analysed these data, taking into account...
