Projective Structure from Two Uncalibrated Images: Structure from Motion and RecRecognition
(1992-09-01)
This paper addresses the problem of recovering relative structure, in the form of an invariant, referred to as projective structure, from two views of a 3D scene. The invariant structure is computed without any prior ...
Data and Model-Driven Selection Using Color Regions
(1992-02-01)
A key problem in model-based object recognition is selection, namely, the problem of determining which regions in the image are likely to come from a single object. In this paper we present an approach that extracts ...
On Directional Selectivity in Vertebrate Retina: An Experimental and Computational Study
(1992-01-01)
This thesis describes an investigation of retinal directional selectivity. We show intracellular (whole-cell patch) recordings in turtle retina which indicate that this computation occurs prior to the ganglion cell, ...
A Coupled Multi-ALU Processing Node for a Highly Parallel Computer
(1992-09-01)
This report describes Processor Coupling, a mechanism for controlling multiple ALUs on a single integrated circuit to exploit both instruction-level and inter-thread parallelism. A compiler statically schedules individual ...
Automated Program Recognition by Graph Parsing
(1992-07-01)
Recognizing standard computational structures (cliches) in a program can help an experienced programmer understand the program. We develop a graph parsing approach to automating program recognition in which programs ...
Probabilistic Analysis of Multistage Interconnection Network Performance
(1992-04-01)
We present methods of calculating the value of two performance parameters for multipath, multistage interconnection networks: the normalized throughput and the probability of successful message transmission. We develop ...
A Novel Approach to Graphics
(1992-02-01)
sWe show that we can optimally represent the set of 2D images producedsby the point features of a rigid 3D model as two lines in twoshigh-dimensional spaces. We then decribe a working recognition systemsin which we represent ...
Recognition and Structure from One 2D Model View: Observations on Prototypes, Object Classes and Symmetries
(1992-02-01)
In this note we discuss how recognition can be achieved from a single 2D model view exploiting prior knowledge of an object's structure (e.g. symmetry). We prove that for any bilaterally symmetric 3D object one non- ...
Local Versus Global Control Laws for Cooperative Agent Teams
(1992-03-01)
The design of the control laws governing the behavior of individual agents is crucial for the successful development of cooperative agent teams. These control laws may utilize a combination of local and/or global ...
Time-Reversible Maxwell's Demon
(1992-09-01)
A time-reversible Maxwell's demon is demonstrated which creates a density difference between two chambers initialized to have equal density. The density difference is estimated theoretically and confirmed by computer ...
