Curved Inertia Frames: Visual Attention and Perceptual Organization Using Convexity and Symmetry
(1991-10-01)
In this paper we present an approach to perceptual organization and attention based on Curved Inertia Frames (C.I.F.), a novel definition of "curved axis of inertia'' tolerant to noisy and spurious data. The definition ...
Perceptual Organization, Figure-Ground, Attention and Saliency
(1991-08-01)
Notions of figure-ground, inside-outside are difficult to define in a computational sense, yet seem intuitively meaningful. We propose that "figure" is an attention-directed region of visual information processing, and ...
Extensions of a Theory of Networks for Approximation and Learning: Outliers and Negative Examples
(1990-07-01)
Learning an input-output mapping from a set of examples can be regarded as synthesizing an approximation of a multi-dimensional function. From this point of view, this form of learning is closely related to regularization ...
Shaping Inputs to Reduce Vibration: A Vector Diagram Approach
(1990-03-01)
This paper describes a method for limiting vibration in flexible systems by shaping the system inputs. Unlike most previous attempts at input shaping, this method does not require an extensive system model or lengthy ...
Automatic Recognition of Tractability in Inference Relations
(1990-02-01)
A procedure is given for recognizing sets of inference rules that generate polynomial time decidable inference relations. The procedure can automatically recognize the tractability of the inference rules underlying ...
The Effect of Indexing on the Complexity of Object Recognition
(1990-04-01)
Many current recognition systems use constrained search to locate objects in cluttered environments. Previous formal analysis has shown that the expected amount of search is quadratic in the number of model and data features, ...
Viewpoint-Specific Representations in Three-Dimensional Object Recognition
(1990-08-01)
We report a series of psychophysical experiments that explore different aspects of the problem of object representation and recognition in human vision. Contrary to the paradigmatic view which holds that the representations ...
Affine Matching with Bounded Sensor Error: A Study of Geometric Hashing and Alignment
(1991-08-01)
Affine transformations are often used in recognition systems, to approximate the effects of perspective projection. The underlying mathematics is for exact feature data, with no positional uncertainty. In practice, ...
The Behavior Language; User's Guide
(1990-04-01)
The Behavior Language is a rule-based real-time parallel robot programming language originally based on ideas from [Brooks 86], [Connell 89], and [Maes 89]. It compiles into a modified and extended version of the ...
Fault-Tolerant Design for Multistage Routing Networks
(1990-04-01)
As the size of digital systems increases, the mean time between single component failures diminishes. To avoid component related failures, large computers must be fault-tolerant. In this paper, we focus on methods for ...
