Disparity-Space Images and Large Occlusion Stereo
A new method for solving the stereo matching problem in the presence of large occlusion is presented. A data structure | the disparity space image | is deened in which we explicitly model the eeects of occlusion regions on the stereo solution. We develop a dynamic programming algorithm that nds matches and occlusions simultaneously. We show that while some cost must be assigned to unmatched pix...
متن کاملVolume perception: Disparity extraction and depth representation in complex three-dimensional environments.
Our sensitivity to binocular disparity is exquisite under the best conditions, typically in uncluttered scenes with few small objects. Yet binocular vision can deliver a very strong impression of depth for complex, cluttered scenes with lots of objects and overlaps. How good is disparity processing under these conditions? Here we explored a novel task: depth volume perception, to study how a gl...
متن کاملModel-space vs. data-space normalization for recursive depth migration
Illumination problems caused by finite-recording aperture and lateral velocity lensing can lead to amplitude fluctuations in migrated images. I calculate both model and data-space weighting functions that compensate for these illumination problems in recursive depth migration results based on downward-contination. These weighting functions can either be applied directly with migration to mitiga...
متن کاملDisparity-defined objects moving in depth do not elicit three-dimensional shape constancy
Observers generally fail to recover three-dimensional shape accurately from binocular disparity. Typically, depth is overestimated at near distances and underestimated at far distances [Johnston, E. B. (1991). Systematic distortions of shape from stereopsis. Vision Research, 31, 1351-1360]. A simple prediction from this is that disparity-defined objects should appear to expand in depth when mov...
متن کاملAurally Aided Visual Search in Three-Dimensional Space
We conducted an experiment to evaluate the effectiveness of spatial audio displays on target acquisition performance. Participants performed a visual search task with and without the aid of a spatial audio display. Potential target locations ranged between plus and minus 180 degrees in azimuth and from -70 degrees to +90 degrees in elevation. Independent variables included the number of visual ...
