Sequence-Seeking and Counter Streams: A Model for Information Processing in the Cortex
(1991-12-01)
This paper presents a model for the general flow in the neocortex. The basic process, called "sequence-seeking," is a search for a sequence of mappings or transformations, linking source and target representations. The ...
Recovering Heading for Visually-Guided Navigation
(1991-06-01)
We present a model for recovering the direction of heading of an observer who is moving relative to a scene that may contain self-moving objects. The model builds upon an algorithm proposed by Rieger and Lawton (1985), ...
Resolving Ambiguity in Nonmonotonic Inheritance Hierarchies
(1991-08-01)
This paper describes a theory of inheritance theories. We present an original theory of inheritance in nonmonotonic hierarchies. The structures on which this theory is based delineate a framework that subsumes most ...
Recovering Three-Dimensional Structure from Motion with Surface Reconstruction
(1991-12-01)
We address the computational role that the construction of a complete surface representation may play in the recovery of 3--D structure from motion. We present a model that combines a feature--based structure--from- ...
Automatic Design of a Maglev Controller in State Space
(1991-12-01)
We describe the automatic synthesis of a global nonlinear controller for stabilizing a magnetic levitation system. The synthesized control system can stabilize the maglev vehicle with large initial displacements from ...
The Matching of Doubly Ambiguous Stereograms
(1991-07-01)
I have previously described psychophysical experiments that involved the perception of many transparent layers, corresponding to multiple matching, in doubly ambiguous random dot stereograms. Additional experiments ...
Intelligence Without Reason
(1991-04-01)
Computers and Thought are the two categories that together define Artificial Intelligence as a discipline. It is generally accepted that work in Artificial Intelligence over the last thirty years has had a strong influence ...
Limitations of Non Model-Based Recognition Schemes
(1991-05-01)
Different approaches to visual object recognition can be divided into two general classes: model-based vs. non model-based schemes. In this paper we establish some limitation on the class of non model-based recognition ...
On The Uniqueness of Correspondence Under Orthographic and Perspective Projections
(1991-12-01)
The task of shape recovery from a motion sequence requires the establishment of correspondence between image points. The two processes, the matching process and the shape recovery one, are traditionally viewed as independent. ...
The Alignment of Objects With Smooth Surfaces: Error Analysis of the Curvature Method
(1991-11-01)
The recognition of objects with smooth bounding surfaces from their contour images is considerably more complicated than that of objects with sharp edges, since in the former case the set of object points that generates ...
