dmax for stereopsis and motion in random dot displays
The upper displacement limit for motion was compared with the upper disparity limit for stereopsis using two-frame random dot kinematograms or briefly presented stereograms. dmax (the disparity/displacement at which subjects make 20% errors in a forced-choice paradigm) was found to be very similar for motion and stereo at all dot densities, and to fall with increasing dot density (0.006% or two...
متن کاملIntegration of stereo and motion
In extracting three-dimensional positional information from images, both static stereo processing and monocular structure-from-motion processing possess shortcomings for a general purpose vision system. A solution to these problems is to use stereo structurefrom-motion processing. This paper addresses the problems of integrating stereo and structure-frommotion data to determine the camera ego-m...
متن کاملNon-rigid Stereo-motion
Using a calibrated stereo pair is a common and practical solution to obtain reliable 3-D reconstructions. In its simpler formulation, once the stereo rig is calibrated, the depth of points in the image is estimated by applying triangulation (Trucco & Verri, 1998). In order to obtain accurate depth estimates, the cameras are usually separated from each other by a significant baseline thus creati...
متن کاملShape and Motion under Varying Illumination: Unifying Structure from Motion, Photometric Stereo, and Multi-view Stereo
♦ Motion cue constrains 3D positions inaccurately for low textured pixels ♦ Photometric cue reveals normals accurately even for moving scenes, despite the noisy motion estimation ♦ Combing both cues recovers moving shape densely Constraints on brightness-varying flow Our formulation extends [Irani99] and applies to features, edges, and textureless regions. Our formulation also subsumes Structur...
متن کاملWhen motion appears stopped: stereo motion standstill.
Motion standstill is different from the usual perceptual experiences associated with objects in motion. In motion standstill, a pattern that is moving quite rapidly is perceived as being motionless, and yet its details are not blurred but clearly visible. We revisited motion standstill in dynamic random-dot stereograms similar to those first used by Julesz and Payne [Julesz B, Payne R (1968) Vi...
