Vision: Simple stereopsis
نویسنده
چکیده
By limiting stereopsis to measuring the distance of moving objects against a stationary background, insects can employ simple stratagems for solving the problems of stereoscopic range finding.

Sequential stereopsis: a simple demonstration
Most people strongly prefer to use back-and-forth eye movements in order to discriminate 3-dimensional distances among targets that are widely separated from each other in direction. This viewing strategy permits sequential stereopsis: a comparison between the foveally-seen pre-saccadic disparity of one target with post-saccadic disparity of the other. This note describes a simple and qualitati...
متن کاملSolving da Vinci stereopsis with depth-edge-selective V2 cells
We propose a new model for da Vinci stereopsis based on a coarse-to-fine disparity energy computation in V1 and disparity-boundary-selective units in V2. Unlike previous work, our model contains only binocular cells, relies on distributed representations of disparity, and has a simple V1-to-V2 feedforward structure. We demonstrate with random-dot stereograms that the V2 stage of our model is ab...
متن کاملارزیابی تغییرات دید عمق دور افراد نرمال در اثر هتروفوریای ایجاد شده به‌وسیله‌ی تست سه میله
Backgrounds and Objective: Stereoacuity is due to a relative difference between images because of retinal disparity. Measurment of stereoacuity is important for diagnosis and treatment of binocular anomalies and noerological problems. The aim of this study was to determine the effect of induced heterophoria by base-out and base-in prisms on distance stereopsis by the Three Needle Test. Material...
متن کاملThe role of transparency in da Vinci stereopsis
The majority of natural scenes contains zones that are visible to one eye only. Past studies have shown that these monocular regions can be seen at a precise depth even though there are no binocular disparities that uniquely constrain their locations in depth. In the so-called da Vinci stereopsis configuration, the monocular region is a vertical line placed next to a binocular rectangular occlu...
متن کاملSequential stereopsis using high-pass spatial frequency filtered textures
Enright [(1995). Perception, 24 (suppl.), 32-33; (1996). Vision Research, 36, 307-312] described a simple piece of equipment for demonstrating a perceptual mechanism he called sequential stereopsis. The equipment requires an observer to set two textured targets seen behind a pair of small viewing ports to appear equi-distant. The principle upon which the apparatus depends is the use of textures...
