The Programmer's Apprentice: A Program Design Scenario
(1987-11-01)
A scenario is used to illustrate the capabilities of a proposed Design Apprentice, focussing on the area of detailed, low-level design. Given a specification, the Design Apprentice will be able to make many of the ...
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 ...
Relaxing the Brightness Constancy Assumption in Computing Optical Flow
(1987-06-01)
Optical flow is the apparent (or perceived) motion of image brightness patterns arising from relative motion of objects and observer. Estimation of the optical flow requires the application of two kinds of constraint: ...
Synapses That Compute Motion
(1987-06-01)
Biophysics of computation is a new field that attempts to characterize the role in information processing of the several biophysical mechanisms in neurons, synapses, and membranes that have been uncovered in recent ...
Hierarchical Object Recognition Using Libraries of Parameterized Model Sub-Parts
(1987-05-01)
This thesis describes the development of a model-based vision system that exploits hierarchies of both object structure and object scale. The focus of the research is to use these hierarchies to achieve robust recognition ...
Finding Texture Boundaries in Images
(1987-06-01)
Texture provides one cue for identifying the physical cause of an intensity edge, such as occlusion, shadow, surface orientation or reflectance change. Marr, Julesz, and others have proposed that texture is represented ...
A Computational Model for Observation in Quantum Mechanics
(1987-03-01)
A computational model of observation in quantum mechanics is presented. The model provides a clean and simple computational paradigm which can be used to illustrate and possibly explain some of the unintuitive and ...
Learning a Color Algorithm from Examples
(1987-06-01)
We show that a color algorithm capable of separating illumination from reflectance in a Mondrian world can be learned from a set of examples. The learned algorithm is equivalent to filtering the image data---in which ...
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 ...
A Multiple Representation Approach to Understanding the Time Behavior of Digital Circuits
(1987-05-01)
We put forth a multiple representation approach to deriving the behavioral model of a digital circuit automatically from its structure and the behavioral simulation models of its components. One representation supports ...
