What Makes a Good Feature?
(1992-04-01)
Using a Bayesian framework, we place bounds on just what features are worth computing if inferences about the world properties are to be made from image data. Previously others have proposed that useful features reflect ...
Chaotic Evolution of the Solar System
(1992-03-01)
The evolution of the entire planetary system has been numerically integrated for a time span of nearly 100 million years. This calculation confirms that the evolution of the solar system as a whole is chaotic, with a ...
Convergence Rates of Approximation by Translates
(1992-03-01)
In this paper we consider the problem of approximating a function belonging to some funtion space Φ by a linear comination of n translates of a given function G. Ussing a lemma by Jones (1990) and Barron (1991) we show ...
The Multi-Scale Veto Model: A Two-Stage Analog Network for Edge Detection and Image Reconstruction
(1992-03-01)
This paper presents the theory behind a model for a two-stage analog network for edge detection and image reconstruction to be implemented in VLSI. Edges are detected in the first stage using the multi-scale veto rule, ...
A Method for Skew-free Distribution of Digital Signals Using Matched Variable Delay Lines
(1992-03-01)
The ability to distribute signals everywhere in a circuit with controlled and known delays is essential in large, high-speed digital systems. We present a technique by which a signal driver can adjust the arrival time ...
Contour Matching Using Local Affine Transformations
(1992-04-01)
Partial constraints are often available in visual processing tasks requiring the matching of contours in two images. We propose a non- iterative scheme to determine contour matches using locally affine transformations. ...
Automatic Analysis and Synthesis of Controllers for Dynamical Systems Based On P
(1992-09-01)
I present a novel design methodology for the synthesis of automatic controllers, together with a computational environment---the Control Engineer's Workbench---integrating a suite of programs that automatically analyze ...
Robot Motion Vision by Fixation
(1992-09-01)
In many motion-vision scenarios, a camera (mounted on a moving vehicle) takes images of an environment to find the "motion'' and shape. We introduce a direct-method called fixation for solving this motion-vision problem ...
Taming Chaotic Circuits
(1992-09-01)
Control algorithms that exploit chaotic behavior can vastly improve the performance of many practical and useful systems. The program Perfect Moment is built around a collection of such techniques. It autonomously ...
A Vector Signal Processing Approach to Color
(1992-01-01)
Surface (Lambertain) color is a useful visual cue for analyzing material composition of scenes. This thesis adopts a signal processing approach to color vision. It represents color images as fields of 3D vectors, from ...
