Bringing the Grandmother Back into the Picture: A Memory-Based View of Object Recognition
(1990-04-01)
We describe experiments with a versatile pictorial prototype based learning scheme for 3D object recognition. The GRBF scheme seems to be amenable to realization in biophysical hardware because the only kind of ...
Extensions of a Theory of Networks for Approximation and Learning: Dimensionality Reduction and Clustering
(1990-04-01)
The theory developed in Poggio and Girosi (1989) shows the equivalence between regularization and a class of three-layer networks that we call regularization networks or Hyper Basis Functions. These networks are also ...
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, ...
Exploiting the Redundancy of a Hand-Arm Robotic System
(1990-10-01)
In this report, a method for exploiting the redundancy of a hand-arm mechanical system for manipulation tasks is illustrated. The basic idea is to try to exploit the different intrinsic capabilities of the arm and hand ...
The Supercomputer Toolkit and Its Applications
(1990-07-01)
The Supercomputer Toolkit is a proposed family of standard hardware and software components from which special-purpose machines can be easily configured. Using the Toolkit, a scientist or an engineer, starting with a ...
Computational Structure of Human Language
(1990-10-01)
The central thesis of this report is that human language is NP-complete. That is, the process of comprehending and producing utterances is bounded above by the class NP, and below by NP-hardness. This constructive ...
Concurrent Aggregates (CA): An Object-Oriented Language for Fine-Grained Message-Passing Machines
(1990-07-01)
Fine-grained parallel machines have the potential for very high speed computation. To program massively-concurrent MIMD machines, programmers need tools for managing complexity. These tools should not restrict program ...
