Interpolating smooth surfaces from boundary conditions is a ubiquitous problem in early visual processing. We describe a solution for an important special case: the interpolation of surfaces that are locally spherical or cylindrical from initial orientation values and constraints on orientation.
We suggest that an appropriate role of early visual processing is to describe a scene in terms of intrinsic (vertical) characteristics?such as range, orientation, reflectance, and incident illumination?of the surface element visible at each point in the image.
Stereo matching using a Lisp Machine implementation of the Baker stereo system developed at Stanford University. The processing is one of edge matching in a hierarchy of long to short image contours, finishing with interedge intensity correlation to yield a dense map of scene disparities.
Summary of the present state of research in scene analysis. It identifies fundamental information-processing principles relevant to representation and use of knowledge in vision and traces limitations of existing programs to compromises of these principles necessitated by extant processors.
The method employed uses regions as basic data and progresses by successive partitioning of the picture toward an interpretable "goal partition", which is then explored by a heuristic decision tree.
In this paper a structural approach to modeling is argued for that explicitly relates image appearance to the scene characteristics from which it arose.

The goal of SRI International’s Digital Earth project was to develop the infrastructure for an open, distributed, multiresolution, 3-D representation of the earth, into which massive quantities of georeferenced information can be embedded.

This report describes interim results of a project to specify special equipment for research in Artificial Intelligence. After surveying several potential users it was decided that there was a need for standardized equipment for robot research.
