Picking Parts out of a Bin
(1983-10-01)
One of the remaining obstacles to the widespread application of industrial robots is their inability to deal with parts that are not precisely positioned. In the case of manual assembly, components are often presented ...
Vertical Image Registration in Stereopsis
(1983-10-01)
Most computational theories of stereopsis require a registration stage prior to stereo matching to reduce the matching to a one-dimensional search. Even after registration, it is critical that the stereo matching process ...
Automatic Synthesis of Fine-Motion Strategies for Robots
(1983-12-01)
The use of active compliance enables robots to carry out tasks in the presence of significant sensing and control errors. Compliant motions are quite difficult for humans to specify, however. Furthermore, robot programs ...
Constructing a Depth Map from Images
(1983-08-01)
This paper describes two methods for constructing a depth map from images. Each method has two stages. First, one or more needle maps are determined using a pair of images. This process employs either the Marr-Poggio-Grimson ...
Maximizing Rigidity: The Incremental Recovery of 3-D Structure from Rigid and Rubbery Motion
(1983-06-01)
The human visual system can extract 3-D shape information of unfamiliar moving objects from their projected transformations. Computational studies of this capacity have established that 3-D shape, can be extracted ...
A Structural Approach to Analogy
(1983-11-01)
There are multiple sorts of reasoning by analogy between two domains; the one with which we are concerned is a type of contextual analogy. The purpose of this paper is to see whether two domains that look analogous ...
The Computational Problem of Motor Control
(1983-05-01)
We review some computational aspects of motor control. The problem of trajectory control is phrased in terms of an efficient representation of the operator connecting joint angles to joint torques. Efficient look-up ...
The SUPDUP Protocol
(1983-07-01)
The SUPDUP protocol provides for login to a remote system over a network with terminal-independent output, so that only the local system need know how to handle the user's terminal. It offers facilities for graphics and ...
A Theoretical Analysis of Electrical Properties of Spines
(1983-04-01)
The electrical properties of a cortical (spiny) pyramidal cell were analyzed on the basis of passive cable theory from measurements made on histological material (Koch, Poggio & Torre 1982). The basis of this analysis ...
The Computation of the Velocity Field
(1983-09-01)
The organization of movement in the changing retinal image provides a valuable source of information for analyzing the environment in terms of objects, their motion in space and their three-dimensional structure. A ...
