Journal ArticleDOI
Contour integration by the human visual system: evidence for a local "association field".
TL;DR: It is suggested that it is possible to take advantage of the redundancy in continuous, but non-aligned features by associating the outputs of filters with similar tuning, and suggest that some of the processes involved in texture segregation may have a similar explanation.
Journal ArticleDOI
The threshold contrast sensitivity function in strabismic amblyopia: Evidence for a two type classification
Robert F. Hess,E.R. Howell +1 more
TL;DR: In this paper, the authors presented threshold contrast sensitivity functions for 10 representative strabismic amblyopes and found that contrast sensitivity is depressed for only high spatial frequencies, including low spatial frequencies.
Journal ArticleDOI
The functional area for summation to threshold for sinusoidal gratings.
E.R. Howell,Robert F. Hess +1 more
TL;DR: This result suggests that there is a functional summation of responses of detecting elements at threshold over an area the size of which is reciprocally related to the spatial frequency.
Journal Article
Vision through cataracts
Robert F. Hess,George C. Woo +1 more
TL;DR: The results indicate that the magnitude and extent of the intra-resolution limit abnormality vary dramatically in cataract subjects and that, for some subjects, vision is abnormal for objects of all sizes.
Journal ArticleDOI
Deficits to global motion processing in human amblyopia
TL;DR: It is shown that there are independent global motion processing deficits in human amblyopia that are unrelated to the contrast sensitivity deficit, and that are more extensive for contrast-defined than for luminance-defined stimuli.
