Ill-Posed Problems and Regularization Analysis in Early Vision
(1984-04-01)One of the best definitions of early vision is that it is inverse optics --- a set of computational problems that both machines and biological organisms have to solve. While in classical optics the problem is to determine ... -
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 ... -
Image Based Rendering Using Algebraic Techniques
(1996-11-01)This paper presents an image-based rendering system using algebraic relations between different views of an object. The system uses pictures of an object taken from known positions. Given three such images it can ... -
Image Chunking: Defining Spatial Building Blocks for Scene Analysis
(1987-08-01)Rapid judgments about the properties and spatial relations of objects are the crux of visually guided interaction with the world. Vision begins, however, with essentially pointwise representations of the scene, such ... -
The Image Dissector "Eyes"
(1969-08-01)This is a collection of data on the construction operation and performance of the two image dissector cameras. Some of this data is useful in deciding whether certain shortcomings are significant for a given application ... -
Image Intensity Understanding
(1975-08-01)Image intensities have been processed traditionally without much regard to how they arise. Typically they are used only to segment an image into regions or to find edge-fragments. Image intensities do carry a great ... -
The Image Irradiance Equation: Its Solution and Application
(1981-06-01)How much information about the shape of an object can be inferred from its image? In particular, can the shape of an object be reconstructed by measuring the light it reflects from points on its surface? These questions ... -
Image-Based View Synthesis
(1997-01-01)We present a new method for rendering novel images of flexible 3D objects from a small number of example images in correspondence. The strength of the method is the ability to synthesize images whose viewing position ... -
Imagination and Situated Cognition
(1991-02-01)A subsumption-based mobile robot is extended to perform cognitive tasks. Following directions, the robot navigates directly to previously unexplored goals. This robot exploits a novel architecture based on the idea ... -
Immediate-Mode Ray-Casting
(1999-06)We propose a simple modification to the classical polygon rasterization pipeline that enables exact, efficient raycasting of bounded implicit surfaces without the use of a global spatial data structure bounding hierarchy. ... -
The Impact of Communication Locality on Large-scale Multiprocessor Performance
(1992-02)As multiprocessor sizes scale and computer architects turn to interconnection networks with non-uniform communication latencies, the lure of exploiting communication locality to increase performance becomes inevitable. ... -
The Impact of Communication Locality on Large-scale Multiprocessor Performance
(1992-06)As multiprocessor sizes scale and computer architects turn to interconnection networks with non-uniform communication latencies, the lure of exploiting communication locality to increase performance becomes inevitable. ... -
The Impact of Layer Assignment Methods on Layout Algorithms for Integrated Circuits
(1983-08)Programs for integrated circuit layout at the module assembly level are typically decomposed into two phases - placement and routing. In this thesis we investigate a third phase which is often implicitly assumed - layer ... -
The Impact of Synchronous Communication on. The Problem of Electing a Leader in a Ring
(1984-04)We consider the problem of electing a leader in a synchronous ring of n processors. We obtain both positive and negative results. One the one hand, we show that if processor ID's are chosen from some countable set, then ... -
Impediments to Universal Preference-based Default Theories
(1989-10)Research on nonmonotonic and default reasoning has identified several important criteria for preferring alternative default inferences. The theories of reasoning based on each of these criteria may uniformly be viewed as ... -
Implementation of a Theory for Inferring Surface Shape from Contours
(1982-08-01)Human vision is adept at inferring the shape of a surface from the image of curves lying across the surface. The strongest impression of 3-D shape derives from parallel (but not necessarily equally spaced) contours. ... -
Implementation of a Theory of Edge Detection
(1980-04-01)This report describes the implementation of a theory of edge detection, proposed by Marr and Hildreth (1979). According to this theory, the image is first processed independently through a set of different size filters, ... -
An Implementation Scheme for Array Operations in Static Data Flow Computers
(1982-05)The mapping of array operations in VAL programs on a static data flow machine with array memory is studied. The flow dependency graph is introduced as a model of array operations in VAL programs. The balancing and ... -
Implementing Asynchronous Distributed Systems Using the IOA Toolkit
(2004-10-06)This document is a report about the capabilities and performance of the IOA Toolkit, and in particularthe tools that provide support for implementing and running distributed systems (checker,composer, code generator). The ... -
Implementing Atomic Data through Indirect Learning in Dynamic Network
(2006-10-12)Developing middleware services for dynamic distributed systems, e.g., ad-hoc networks, is a challenging task given that suchservices must deal with communicating devices that may join and leave the system, and fail or ...
