Relative Orientation
(1987-09-01)
Before corresponding points in images taken with two cameras can be used to recover distances to objects in a scene, one has to determine the position and orientation of one camera relative to the other. This is the ...
On the Recognition of Parameterized Objects
(1987-10-01)
Determining the identity and pose of occluded objects from noisy data is a critical step in interacting intelligently with an unstructured environment. Previous work has shown that local measurements of position and ...
On the Recognition of Curved Objects
(1987-07-01)
Determining the identity and pose of occluded objects from noisy data is a critical part of a system's intelligent interaction with an unstructured environment. Previous work has shown that local measurements of the ...
Abstraction in Numerical Methods
(1987-10-01)
We illustrate how the liberal use of high-order procedural abstractions and infinite streams helps us to express some of the vocabulary and methods of numerical analysis. We develop a software toolbox encapsulating the ...
Energy Functions for Early Vision and Analog Networks
(1987-11-01)
This paper describes attempts to model the modules of early vision in terms of minimizing energy functions, in particular energy functions allowing discontinuities in the solution. It examines the success of using ...
Rigidity and Smoothness of Motion
(1987-11-01)
sMany theories of structure from motion divide the process into twosparts which are solved using different assumptions. Smoothness of thesvelocity field is often assumed to solve the motion correspondencesproblem, and then ...
Lisp: A Language for Stratified Design
(1987-08-01)
We exhibit programs that illustrate the power of Lisp as a language for expressing the design and organization of computational systems. The examples are chosen to highlight the importance of abstraction in program ...
Principle-Based Parsing for Machine Translation
(1987-12-01)
Many syntactic parsing strategies for machine translation systems are based entirely on context-free grammars. These parsers require an overwhelming number of rules; thus, translation systems using rule-based parsers ...
Dimensionality-Reduction Using Connectionist Networks
(1987-01-01)
This paper presents a method for using the self-organizing properties of connectionist networks of simple computing elements to discover a particular type of constraint in multidimensional data. The method performs ...
Understanding Bandwidth Limitations in Robot Force Control
(1987-08-01)
This paper provides an analytical overview of the dynamics involved in force control. Models are developed which demonstrate, for the one-axis explicit force control case, the effects on system closed-loop bandwidth ...
