A Vision Chip
(1981-05-01)
Some well understood and well justified algorithms for early visual processing must be implemented in hardware for later visual processing to be studied. This paper describes the design and hardware implementation of ...
The Image Irradiance Equation: Its Solution and Application
(1981-06-01)
How much information about the shape of an object can be inferred from its image? In particular, can the shape of an object be reconstructed by measuring the light it reflects from points on its surface? These questions ...
Inspection Methods in Programming
(1981-06-01)
The work reported here lies in the area of overlap between artificial intelligence software engineering. As research in artificial intelligence, it is a step towards a model of problem solving in the domain of ...
Foundations of Actor Semantics
(1981-05-01)
The actor message-passing model of concurrent computation has inspired new ideas in the areas of knowledge-based systems, programming languages and their semantics, and computer systems architecture. The model itself ...
The Representation of Image Texture
(1981-09-01)
This thesis explores how to represent image texture in order to obtain information about the geometry and structure of surfaces, with particular emphasis on locating surface discontinuities. Theoretical and psychophysical ...
An Accountable Source-To-Source Transformation System
(1981-06-01)
Though one is led to believe that program transformation systems which perform source-to-source transformations enable the user to understand and appreciate the resulting source program, this is not always the case. ...
The Implicit Constraints of the Primal Sketch
(1981-10-01)
Computational theories of structure-from-motion and stereo vision only specify the computation of three-dimensional surface information at points in the image at which the irradiance changes. Yet, the visual perception ...
The Scientific Community Metaphor
(1981-01-01)
Scientific communnities have proven to be extremely successful at solving problems. They are inherently parallel systems and their macroscopic nature makes them amenable to careful study. In this paper the character of ...
Marr's Approach to Vision
(1981-08-01)
In the last seven years a new computational approach has led to promising advances in the understanding of biological visual perception. The foundations of the approach are largely due to the work of a single man, ...
Passive Navigation
(1981-11-01)
A method is proposed for determining the motion of a body relative to a fixed environment using the changing image seen by a camera attached to the body. The optical flow in the image plane is the input, while the ...
