A Parallelizing Compiler Based on Partial Evaluation
(1993-07-01)
We constructed a parallelizing compiler that utilizes partial evaluation to achieve efficient parallel object code from very high-level data independent source programs. On several important scientific applications, ...
Robust Photo-topography by Fusing Shape-from-Shading and Stereo
(1993-02-01)
Methods for fusing two computer vision methods are discussed and several example algorithms are presented to illustrate the variational method of fusing algorithms. The example algorithms seek to determine planet ...
Equivalence and Reduction of Hidden Markov Models
(1993-01-01)
This report studies when and why two Hidden Markov Models (HMMs) may represent the same stochastic process. HMMs are characterized in terms of equivalence classes whose elements represent identical stochastic processes. ...
Recognizing 3-D Objects Using 2-D Images
(1993-04-01)
We discuss a strategy for visual recognition by forming groups of salient image features, and then using these groups to index into a data base to find all of the matching groups of model features. We discuss the most ...
Priors Stabilizers and Basis Functions: From Regularization to Radial, Tensor and Additive Splines
(1993-06-01)
We had previously shown that regularization principles lead to approximation schemes, as Radial Basis Functions, which are equivalent to networks with one layer of hidden units, called Regularization Networks. In this ...
Geometric Structure of the Adaptive Controller of the Human Arm
(1993-07-01)
The objects with which the hand interacts with may significantly change the dynamics of the arm. How does the brain adapt control of arm movements to this new dynamic? We show that adaptation is via composition of a ...
Geometric and Algebraic Aspects of 3D Affine and Projective Structures from Perspective 2D Views
(1993-07-01)
We investigate the differences --- conceptually and algorithmically --- between affine and projective frameworks for the tasks of visual recognition and reconstruction from perspective views. It is shown that an affine ...
Example Based Image Analysis and Synthesis
(1993-11-01)
Image analysis and graphics synthesis can be achieved with learning techniques using directly image examples without physically-based, 3D models. In our technique: -- the mapping from novel images to a vector of "pose" ...
Conditions for Viewpoint Dependent Face Recognition
(1993-08-01)
Poggio and Vetter (1992) showed that learning one view of a bilaterally symmetric object could be sufficient for its recognition, if this view allows the computation of a symmetric, "virtual," view. Faces are roughly ...
Measure Fields for Function Approximation
(1993-06-01)
The computation of a piecewise smooth function that approximates a finite set of data points may be decomposed into two decoupled tasks: first, the computation of the locally smooth models, and hence, the segmentation ...
