Integration, segregation, and binocular combination.
Journal Title: Journal of the Optical Society of America A: Optics, Image Science & Vision - Year 2005, Vol 22, Issue 1
Abstract
The human visual system can accurately judge the mean of a distributionof different orientation samples. We ask whether the site of this integration is before or after thesites of binocular combination and disparity processing. Furthermore, we are interested in whether theefficiency with which local orientation information is integrated depends on the eye of origin. Our resultssuggest that orientation integration occurs after binocular integration but before disparity coding.We show that the effectiveness of added orientation noise is not only less than expected on signal ornoise grounds but also that it depends on the dominance of the eye to which it is presented, suggestingan interocular opponent interaction in which the dominant eye input has higher gain.

Integration of first- and second-order orientation.
The problem of how visual information such as orientation is combined acrossspace bears on key visual abiities, such as texture perception. Orientation signals can be derived fromboth luminance and contrast, but it is no...
Computer-generated holograms of three-dimensional objects synthesized fromtheir multiple angular viewpoints.
Synthesizing computer-generated holograms (CGHs) of a general three-dimensional(3D) object is usually a heavy computational task. We propose and demonstrate a new algorithm for computingCGHs of 3D objects. In our scheme,...

Three-dimensional relationship between high-order root-mean-square wavefront error, pupil diameter, and aging.
We report root-mean-square (RMS) wavefront error (WFE) for individual aberrations and cumulative high-order (HO) RMS WFE for the normal human eye as a function of age by decade and pupil diameter in 1 mm steps from 3 to...
