Understanding in Incomplete Worlds
(1978-05-01)
Most real world domains differ from the micro-worlds traditionally used in A.I. in that they have an incomplete factual database which changes over time. Understanding in these domains can be thought of as the generation ...
Photometric Stereo
(1978-06-01)
Traditional stereo techniques determine range by relating two images of an object viewed from different directions. If the correspondence between picture elements is known, then distance to the object can be calculated ...

Destriping Satellite Images
(1978-03-01)
Before satellite images obtained with multiple image sensors can be used in image analysis, corrections must be introduced for the differences in transfer functions on these sensors. Methods are here presented for ...
The Interpretation of Structure From Motion
(1976-10-01)
The interpretation of structure from motion is examined from a computational point of view. The question addressed is how the 3-D structure and motion of objects can be inferred from the 2-D transformations of their ...
