Fine-to-coarse scale disambiguation in stereopsis
Spatial frequency selectivity has been incorporated into various theories of stereo matching, along with spatial scale interactions operating from coarse-to-fine spatial scales. We concentrate here on the role of fine scale information in the stereo matching process and show that fine scale information is capable of disambiguating matches made at coarser scales. An ambiguous coarse scale stimul...
متن کاملCoarse-fine dichotomies in human stereopsis
There is a long history of research into depth percepts from very large disparities, beyond the fusion limit. Such diplopic stimuli have repeatedly been shown to provide reliable depth percepts. A number of researchers have pointed to differences between the processing of small and large disparities, arguing that they are subserved by distinct neural mechanisms. Other studies have pointed to a ...
متن کاملOn the typical development of stereopsis: Fine and coarse processing
Stereoscopic depth perception may be obtained from small retinal disparities that can be fused for single vision (fine stereopsis), but reliable depth information is also obtained from larger disparities that produce double vision (coarse stereopsis). While there is some evidence that stereoacuity improves with age, little is known about the development and maturation of coarse stereopsis. Here...
متن کاملStereopsis
When she becomes dominant her body changes so that she becomes physiologically and morphologically distinct from other non-reproductive female ‘workers’, even her bone structure changes. Mole-rats were thought to be the only mammal to do this, but it has since been discovered that female meerkats also develop elongated vertebra when they become dominant breeders. As well as reproductives, there...
متن کاملOcular contributions to age-related loss in coarse stereopsis.
PURPOSE To determine the basis for the dramatic decline in coarse stereopsis that occurs with age. METHODS The Frisby test was used to assess stereopsis in a large sample of randomly selected persons over the age of 58 years. A number of other vision functions were also assessed in the same persons. The data were used to address the question of whether the decline in stereopsis reflects age-r...
