Non-Monotonic Logic I
(1979-01-01)
"Non-monotonic" logical systems are logics in which the introduction of new axioms can invalidate old theorems. Such logics are very important in modeling the beliefs of active processes which, acting in the presence ...
Calculating the Reflectance Map
(1978-10-01)
It appears that the development of machine vision may benefit from a detailed understanding of the imaging process. The reflectance map, showing scene radiance as a function of surface gradient, has proved to be helpful ...
Determining Shape and Reflectance Using Multiple Images
(1978-08-01)
Distributions of surface orientation and reflectance factor on the surface of an object can be determined from scene radiances observed by a fixed sensor under varying lighting conditions. Such techniques have potential ...
Constraints
(1978-11-01)
We present an interactive system organized around networks of constraints rather than the programs which manipulate them. We describe a language of hierarchical constraint networks. We describe one method of deriving ...
Information Prosthetics for the Handicapped
(1978-09-01)
In this proposal we describe a technological step towards the realization of INFORMATION PROSTHETICS. Our primary focus is on using rather than making the technology. Specifically, our goal is to transpose for the use ...
Bandpass Channels, Zero-Crossings, and Early Visual Information Processing
(1978-09-01)
A recent advance by B.F. Logan in the theory of one octave bandpass signals may throw new light on spatial-frequency-tuned channels in early visual information processing.
Reflectance Map Techniques for Analyzing Surface Defects in Metal Castings
(1978-06-01)
This report explores the relation between image intensity and object shape. It is shown that image intensity is related to surface orientation and that a variation in image intensity is related to surface curvature. ...
Shape from Shading: A Method for Obtaining the Shape of a Smooth Opaque Object from One View
(1970-11-01)
A method will be described for finding the shape of a smooth apaque object form a monocular image, given a knowledge of the surface photometry, the position of the lightsource and certain auxiliary information to ...
Dependency Directed Reasoning for Complex Program Understanding
(1979-04-01)
Artificial Intelligence research involves the creation of extremely complex programs which must possess the capability to introspect, learn, and improve their expertise. Any truly intelligent program must be able to ...
Information Processing and Transmission in Cellular Automata
(1971-01-01)
A cellular automaton is an iterative array of very simple identical information processing machines called cells. Each cell can communicate with neighboring cells. At discrete moments of time the cells can change from ...
