The factorization method, first developed by Tomasi and Kanade, recovers both the shape of an object and its motion from a sequence of images, using many images and tracking many feature points to obtain highly redundant feature position information. The method robustly processes the feature trajectory information using singular value decomposition (SVD),(More)
Neurosensory tactile functions were investigated in human subjects by two different and complementary experimental approaches. First, a conventional psychophysical method (two-point gap discrimination) was used to determine the tactile discrimination threshold by analyzing the subjects' ability to detect a gap of variable width between two contact points(More)
Ketamine is normally considered as being anti-dysrhythmic. A case report is presented here in which small subanaesthetic doses of ketamine were administered to reinforce spinal analgesia. Initial doses were followed by a dysrhythmia, which appeared to be repeatedly counteracted by further small doses of the drug. The cardiac pharmacology of ketamine is(More)
We describe a system that computes the three-dimensional (3D) shape of a spacecraft from a sequence of uncalibrated, two-dimensional images. While the mathematics of multi-view geometry is well understood, building a system that accurately recovers 3D shape from real imagery remains an art. A novel aspect of our approach is the combination of algorithms(More)
