Journal ArticleDOI
Incremental rigidity scheme for recovering structure from motion: position-based versus velocity-based formulations
TL;DR: In this paper, the authors present formulations of Ullman's method that use velocity information and perspective projection in the recovery of structure, and show that the velocity-based formulations provide a rough estimate of structure quickly but are not robust over an extended time.
Journal ArticleDOI
The Perceptual Buildup of Three-Dimensional Structure from Motion
TL;DR: The main conclusions are that the human visual system can derive an accurate model of the relative depths of moving points, even in the presence of noise in their image positions, and the accuracy of the 3-D model improves with time, eventually reaching a plateau.
Journal ArticleDOI
Structure-from-motion: Perceptual evidence for surface interpolation
TL;DR: It is argued that the perceptual interpretation of the object's boundaries influences the surface interpolation process and that in this process the visual system looses access to the identity of the individual features that make up the surface.
Journal ArticleDOI
Recovering Three-Dimensional Structure from Motion with Surface Reconstruction
TL;DR: A model is presented that combines a feature-based structure-from-motion algorithm with a smooth surface interpolation mechanism that allows multiple surfaces to be represented in a given viewing direction, incorporates constraints on surface structure from object boundaries, and segregates image features onto multiple surfaces on the basis of their 2-D image motion.
