Any Dimensional Reconstruction from Hyperplanar Projections
(1984-10-01)
In this paper we examine the reconstruction of functions of any dimension from hyperplanar projections. This is a generalization of a problem that has generated much interest recently, especially in the field of medical ...
Simplified Grasping and Manipulation with Dextrous Robot Hands
(1984-11-01)
A method is presented for stably grasping 2 dimensional polygonal objects with a dextrous hand when object models are not avaiable. Basic constraints on object vertex angles are found for feasible grasping with two fingers. ...
Codon Constraints on Closed 2D Shapes
(1984-05-01)
Codons are simple primitives for describing plane curves. They thus are primarily image-based descriptors. Yet they have the power to capture important information about the 3-D world, such as making part boundaries ...
Collision Detection for Moving Polyhedra
(1984-10-01)
We consider the problem of moving a three dimensional solid object among polyhedral obstacles. The traditional formulation of configuration space for this problem uses three translational parameters and three angles ...
A Theoretical Analysis of the Electrical Properties of a X-Cell in the Cat's LGN
(1984-03-01)
Electron microscope studies of relay cells in the lateral geniculate nucleus of the CAT have shown that the retinal input of X-cells is associated with a special synaptic circuitry, termed the spine-triad complex. The ...
PRISM: A Practical Real-Time Imaging Stereo Matcher
(1984-05-01)
A binocular-stereo-matching algorithm for making rapid visual range measurements in noisy images is described. This technique is developed for application to problems in robotics where noise tolerance, reliability, and ...
An Information Storage Mechanism: Calcium and Spines
(1984-04-01)
This proposal addresses some of the biophysical events possibly underlying fast activity-dependent changes in synaptic efficiency. Dendritic spines in the cortex have attracted increased attention over the last years ...
An Analog Model of Computation for the Ill-Posed Problems of Early Vision
(1984-05-01)
A large gap exists at present between computational theories of vision and their possible implementation in neural hardware. The model of computation provided by the digital computer is clearly unsatisfactory for the ...
The Coordination of Arm Movements: An Experimentally Confirmed Mathematical Model
(1984-11-01)
This paper presents studies of the coordination f voluntary human arm movements. A mathematical model is formulated which is shown to predict both the qualitative features and the quantitative details observed ...
Ill-Posed Problems and Regularization Analysis in Early Vision
(1984-04-01)
One of the best definitions of early vision is that it is inverse optics --- a set of computational problems that both machines and biological organisms have to solve. While in classical optics the problem is to determine ...
