Recognition and Structure from One 2D Model View: Observations on Prototypes, Object Classes and Symmetries
(1992-02-01)
In this note we discuss how recognition can be achieved from a single 2D model view exploiting prior knowledge of an object's structure (e.g. symmetry). We prove that for any bilaterally symmetric 3D object one non- ...
Local Versus Global Control Laws for Cooperative Agent Teams
(1992-03-01)
The design of the control laws governing the behavior of individual agents is crucial for the successful development of cooperative agent teams. These control laws may utilize a combination of local and/or global ...
Time-Reversible Maxwell's Demon
(1992-09-01)
A time-reversible Maxwell's demon is demonstrated which creates a density difference between two chambers initialized to have equal density. The density difference is estimated theoretically and confirmed by computer ...
Task and Object Learning in Visual Recognition
(1991-01-01)
Human performance in object recognition changes with practice, even in the absence of feedback to the subject. The nature of the change can reveal important properties of the process of recognition. We report an ...
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 ...
On the Shifter Hyposthesis for the Elimination of Motion Blur
(1990-08-01)
Moving objects may stimulate many retinal photoreceptors within the integration time of the receptors without motion blur being experienced. Anderson and vanEssen (1987) suggested that the neuronal representation of ...
Direct Estimation of Structure and Motion from Multiple Frames
(1990-03-01)
This paper presents a method for the estimation of scene structure and camera motion from a sequence of images. This approach is fundamentally new. No computation of optical flow or feature correspondences is required. ...
Direct Recovery of Motion and Shape in the General Case by Fixation
(1990-03-01)
This work introduces a direct method called FIXATION for solving the general motion vision problem. This Fixation method results in a constraint equation between translational and rotational velocities that in combination ...
A Model for Rivalry Between Cognitive Contours
(1990-06-01)
The interactions between illusory and real contours have been inves- tigated under monocular, binocular and dichoptic conditions. Results show that under all three presentation conditions, periodic alternations, ...
