Perspective Projection Invariants
(1986-02-01)An important part of stereo vision consists of finding and matching points in two images which correspond to the same physical element in the scene. We show that zeros of curvature of curves are perspective projection ... -
Perspectives on the Use of the Internet in Sri Lanka
(2000-11)The survey examines the use of computers and the Internet in Sri Lanka from the perspective of the Internet Service Provider (ISP) members. It attempts to describe the general nature of IT use in terms of the availability, ... -
A Perturbation Scheme for Spherical Arrangements with Application to Molecular Modeling
(1997-12-01)We describe a software package for computing and manipulating the subdivision of a sphere by a collection of (not necessarily great) circles and for computing the boundary surface of the union of spheres. We present problems ... -
Peter Samson's Music Processor, BIG
(1970-07-01)The contents of this memo are: commands which create a name, commands which create music, playing commands, plotting commands, general utility commands, debugging commands (in relation to relics of the past, features you ... -
Petri Net Language
(1976-03)In a labeled Petri Net we assign symbols from an alphabet to some or all the transitions of a Petri Net. To each firing sequence of such a Labeled Petri Net corresponds to a string over the alphabet. We study the languages ... -
Phantom Stacks: If You Look Too Hard, They Aren't There
(1980-07-01)A Stack is a very efficient way of allocating and deallocating memory, but it works only with a restricted pattern of usage. Garbage collection is completely flexible but comparatively costly. The implementation of ... -
Phase Space Navigator: Towards Automating Control Synthesis in Phase Spaces for Nonlinear Control Systems
(1991-04-01)We develop a novel autonomous control synthesis strategy called Phase Space Navigator for the automatic synthesis of nonlinear control systems. The Phase Space Navigator generates global control laws by synthesizing ... -
Phased Computation Graphs in the Polyhedral Model
(2002-08)We present a translation scheme that allows a broad class of dataflow graphs to be considered under the optimization framework of the polyhedral model. The input to our analysis is a Phased Computation Graph, which we ... -
PhD Thesis Proposal: Human-Machine Collaborative Optimization via Apprenticeship Scheduling
(2015-07-02)Resource optimization in health care, manufacturing, and military operations requires the careful choreography of people and equipment to effectively fulfill the responsibilities of the profession. However, resource ... -
The PHD: A Planar, Harmonic Drive Robot for Joint Torque Control
(1990-05-01)This thesis details the development of a model of a seven degree of freedom manipulator for position control. Then, it goes on to discuss the design and construction of a the PHD, a robot built to serve two purposes: ... -
Phonetic Classification Using Hierarchical, Feed-forward, Spectro-temporal Patch-based Architectures
(2007-02-01)A preliminary set of experiments are described in which a biologically-inspired computer vision system (Serre, Wolf et al. 2005; Serre 2006; Serre, Oliva et al. 2006; Serre, Wolf et al. 2006) designed for visual object ... -
Phonetic Classification Using Hierarchical, Feed-forward, Spectro-temporal Patch-based Architectures
(2007-03-21)A preliminary set of experiments are described in which a biologically-inspired computer vision system (Serre, Wolf et al. 2005; Serre 2006; Serre, Oliva et al. 2006; Serre, Wolf et al. 2006) designed for visual object ... -
Phonological Parsing for Bi-directional Letter-to-Sound/Sound-to-Letter Generation
(1995-06)This thesis proposes a unified framework for integrating a variety of linguistic knowledge sources for representing speech, in order to facilitiate their concurrent utilization in spoken language systems. The feasibility ... -
Photometric Stereo
(1978-06-01)Traditional stereo techniques determine range by relating two images of an object viewed from different directions. If the correspondence between picture elements is known, then distance to the object can be calculated ... -
Physical Random Functions
(2003-02)In general, secure protocols assume that participants are able to maintain secret key information. In practice, this assumption is often incorrect as an increasing number of devices are vulnerable to physical attacks. ... -
Physiology and Psychology of Color Vision -- A Review
(1976-08-01)This paper is a review of the anatomy, physiology, and psychology of human color vision. -
Pi: A Parallel Architecture Interface for Multi-Model Execution
(1990-05-01)This thesis defines Pi, a parallel architecture interface that separates model and machine issues, allowing them to be addressed independently. This provides greater flexibility for both the model and machine builder. ... -
Picking Parts out of a Bin
(1983-10-01)One of the remaining obstacles to the widespread application of industrial robots is their inability to deal with parts that are not precisely positioned. In the case of manual assembly, components are often presented ... -
Picking Up an Object from a Pile of Objects
(1983-05-01)This paper describes a hand-eye system we developed to perform the binpicking task. Two basic tools are employed: the photometric stereo method and the extended Gaussian image. The photometric stereo method generates ... -
PICPAC: A PDP-6 Picture Package
(1967-10-01)PICPAC is a program to be used for manipulating pictures of real-world scenes. It operated under ITS (the Incompatible Time-Sharing System) under control of a simple on-line command language. It includes facilities for ...
