Characterization of Joint-Interpolated Arm Movements
(1985-06-01)
Two possible sets of planning variables for human arm movement are point angles and hand position. Although one might expect these possibilities to be mutually exclusive, recently an apparently contradictory set of ...
Shape from Shading, Occlusion and Texture
(1987-05-01)
Shape from Shading, Occlusion and Texture are three important sources of depth information. We review and summarize work done on these modules.
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 ...
Artificial Intelligence and Robotics
(1984-02-01)
Since Robotics is the field concerned with the connection of perception to action, Artificial Intelligence must have a central role in Robotics if the connection is to be intelligent. Artificial Intelligence addresses ...
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 ...
A Method for Computing Spectral Reflectance
(1984-12-01)
Psychophysical experiments show that the perceived colour of an object is relatively independent of the spectrum of the incident illumination and depends only on the surface reflectance. We demonstrate a possible ...
The Curvature Primal Sketch
(1984-02-01)
In this paper we introduce a novel representation of the significant changes in curvature along the bounding contour of planar shape. We call the representation the curvature primal sketch. We describe an implemented ...
Computations Underlying the Measurement of Visual Motion
(1984-03-01)
The organization of movement in a changing image provides a valuable source of information for analyzing the environment in terms of objects, their motion in space, and their three-dimensional structure. This movement ...
