The Visual Perception of 3-Dimensional Structure from Motion
One of the most perplexing phenomena in the study of human vision is the ability of observers to perceive the 3-dimensional layout of the environment from patterns of light that project onto the retina. Indeed, were it not for the facts of our day-to-day experiences, it would be tempting to conclude that the perception of 3dimensional form is a mathematical impossibility, since the properties o...
متن کاملPerception of three-dimensional structure from motion.
The ability to perceive the 3-D shape of objects solely from motion cues is referred to as structure-from-motion perception. Recent experiments indicate how this remarkable perceptual attribute is computed by the brains of primates. This computation proceeds in at least two stages, one in which motion measurements are made and another in which moving surfaces are reconstructed. The middle tempo...
متن کاملApparent Opacity Aaects Perception of Structure from Motion
It is well known that the human visual system can reconstruct depth from simple random-dot displays given motion information. This fact has lent support to the notion that structure from stereo and motion systems rely on low-level primitives or tokens, such as edges, derived from image intensities. In contrast, the judgment of surface attributes such as transparency or opacity is often consider...
متن کاملThe Perception of Motion and Structure in Structure-from-motion: Comparisons of Affine and Euclidean Formulations
I investigated the discrimination of rigid from nonrigid structure and the perception of affine stretches along the line of sight [Norman & Todd (1993). Perception and Psychophysics, 53, pp. 279-291]. Investigations of performance at discriminating rigid from nonrigid structure showed that performance improved when number of views and amount of simulated three-dimensional nonrigidity increased....
متن کاملAffine Structure from Translational Motion in Image Sequences
In this paper a method for obtaining affine structure from an image sequence taken by a translating camera with constant intrinsic parameters is presented. A general geometric constraint, expressed using the camera matrices, is derived and this constraint is used in a least squares solution of the problem. The first step is to obtain a projective reconstruction, in the form of a sequence of cam...
