Detecting binocular 3D motion in static 3D noise: no effect of viewing distance.
Relative binocular disparity cannot tell us the absolute 3D shape of an object, nor the 3D trajectory of its motion, unless the visual system has independent access to how far away the object is at any moment. Indeed, as the viewing distance is changed, the same disparate retinal motions will correspond to very different real 3D trajectories. In this paper we were interested in whether binocula...
متن کامل3D Hand Motion Evaluation Using HMM
Gesture and motion recognition are needed for a variety of applications. The use of human hand motions as a natural interface tool has motivated researchers to conduct research in the modeling, analysis and recognition of various hand movements. In particular, human-computer intelligent interaction has been a focus of research in vision-based gesture recognition. In this work, we introduce a 3-...
متن کاملTesting Probabilistic Models of Binocular 3d Motion Perception
Geometric constraints for the perception of three-dimensional (3D) binocular motion are discussed in a probabilistic framework. Two alternative Bayesian models of binocular integration are put forward to explain perceptual bias under uncertainty. The models exploit biologically plausible constraints of local motion and disparity processing in a binocular viewing geometry. Results from computer ...
متن کاملOn the Inverse Problem of Binocular 3D Motion Perception
It is shown that existing processing schemes of 3D motion perception such as interocular velocity difference, changing disparity over time, as well as joint encoding of motion and disparity, do not offer a general solution to the inverse optics problem of local binocular 3D motion. Instead we suggest that local velocity constraints in combination with binocular disparity and other depth cues pr...
متن کاملOptimal Combination of the Binocular Cues to 3D Motion.
PURPOSE Perception necessarily entails combining separate sensory estimates into a single coherent whole. The perception of three-dimensional (3D) motion, for instance, can rely on two binocular cues: one related to the change in binocular disparity over time (CD) and the other related to interocular velocity differences (IOVD). Although previous work has shown that neither cue is strictly nece...
