Ill-Posed Problems in Early Vision
(1987-05-01)
The first processing stage in computational vision, also called early vision, consists in decoding 2D images in terms of properties of 3D surfaces. Early vision includes problems such as the recovery of motion and ...
Extensions of a Theory of Networks for Approximation and Learning: Outliers and Negative Examples
(1990-07-01)
Learning an input-output mapping from a set of examples can be regarded as synthesizing an approximation of a multi-dimensional function. From this point of view, this form of learning is closely related to regularization ...
An Information Processing Approach to Understanding the Visual Cortex
(1980-04-01)
An outline description is given of the experimental work on the visual acuity and hyperacuity of human beings. The very high resolution achieved in hyperacuity corresponds to a fraction of the spacing between adjacent ...
An Optimal Scale for Edge Detection
(1988-09-01)
Many problems in early vision are ill posed. Edge detection is a typical example. This paper applies regularization techniques to the problem of edge detection. We derive an optimal filter for edge detection with a ...
Optical Flow From 1D Correlation: Application to a Simple Time-To-Crash Detector
(1993-10-01)
In the first part of this paper we show that a new technique exploiting 1D correlation of 2D or even 1D patches between successive frames may be sufficient to compute a satisfactory estimation of the optical flow field. ...
Marr's Approach to Vision
(1981-08-01)
In the last seven years a new computational approach has led to promising advances in the understanding of biological visual perception. The foundations of the approach are largely due to the work of a single man, ...
Regularization Theory and Shape Constraints
(1986-09-01)
Many problems of early vision are ill-posed; to recover unique stable solutions regularization techniques can be used. These techniques lead to meaningful results, provided that solutions belong to suitable compact ...
Visual Integration and Detection of Discontinuities: The Key Role of Intensity Edges
(1987-10-01)
Integration of several vision modules is likely to be one of the keys to the power and robustness of the human visual system. The problem of integrating early vision cues is also emerging as a central problem in current ...
The Computational Problem of Motor Control
(1983-05-01)
We review some computational aspects of motor control. The problem of trajectory control is phrased in terms of an efficient representation of the operator connecting joint angles to joint torques. Efficient look-up ...
An Analog Model of Computation for the Ill-Posed Problems of Early Vision
(1984-05-01)
A large gap exists at present between computational theories of vision and their possible implementation in neural hardware. The model of computation provided by the digital computer is clearly unsatisfactory for the ...
