Relaxing the Brightness Constancy Assumption in Computing Optical Flow
(1987-06-01)
Optical flow is the apparent (or perceived) motion of image brightness patterns arising from relative motion of objects and observer. Estimation of the optical flow requires the application of two kinds of constraint: ...
Utilizing Dynamic Stability to Orient Parts
(1988-02-01)
The intent of this research is to study the dynamic behavior of a solid body resting on a moving surface. Results of the study are then used to propose methods for controlling the orientation of parts in preparation ...
Synapses That Compute Motion
(1987-06-01)
Biophysics of computation is a new field that attempts to characterize the role in information processing of the several biophysical mechanisms in neurons, synapses, and membranes that have been uncovered in recent ...
Knowledge Base Integration: What Can We Learn from Database Integration Research?
(1988-01-01)
This paper examines the issues and the solutions that have been studied in database (DB) integration research and tries to draw lessons from them for knowledge base (KB) integration.
Understanding and Modeling the Behavior of a Harmonic Drive Gear Transmission
(1992-05-01)
In my research, I have performed an extensive experimental investigation of harmonic-drive properties such as stiffness, friction, and kinematic error. From my experimental results, I have found that these properties ...
Robust and Efficient 3D Recognition by Alignment
(1992-09-01)
Alignment is a prevalent approach for recognizing 3D objects in 2D images. A major problem with current implementations is how to robustly handle errors that propagate from uncertainties in the locations of image ...
A Lifetime-based Garbage Collector for LISP Systems on General-Purpose Computers
(1988-02-01)
Garbage collector performance in LISP systems on custom hardware has been substantially improved by the adoption of lifetime-based garbage collection techniques. To date, however, successful lifetime-based garbage ...
A Parallelizing Compiler Based on Partial Evaluation
(1993-07-01)
We constructed a parallelizing compiler that utilizes partial evaluation to achieve efficient parallel object code from very high-level data independent source programs. On several important scientific applications, ...
Minimizing Residual Vibrations in Flexible Systems
(1992-06-01)
Residual vibrations degrade the performance of many systems. Due to the lightweight and flexible nature of space structures, controlling residual vibrations is especially difficult. Also, systems such as the Space ...
Robust Photo-topography by Fusing Shape-from-Shading and Stereo
(1993-02-01)
Methods for fusing two computer vision methods are discussed and several example algorithms are presented to illustrate the variational method of fusing algorithms. The example algorithms seek to determine planet ...
