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. ...
Machine Recognition as Representation and Search
(1989-12-01)
Generality, representation, and control have been the central issues in machine recognition. Model-based recognition is the search for consistent matches of the model and image features. We present a comparative ...
Limits of Precision for Human Eye Motor Control
(1989-11-01)
Dichoptic presentation of vernier stimuli, i.e., one segment to each eye, yielded three times higher thresholds than binocular presentation, mainly due to uncorrelated movements of both eyes. Thresholds allow one to ...
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 ...
Computation of Texture and Stereoscopic Depth in Humans
(1989-10-01)
The computation of texture and of stereoscopic depth is limited by a number of factors in the design of the optical front-end and subsequent processing stages in humans and machines. A number of limiting factors in ...
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, ...
