This paper discusses the problem of context-free position estimation using a stereo vision system with moveable eyes. Exact and approximate equations are developed linking position to measureable quantities of the ...

This paper discusses the problem of context-free position estimation using a stereo vision system with moveable eyes. Exact and approximate equations are developed linking position to measureable quantities of the image-space, ...

To recognize a previously seen object, the visual system must overcome the variability in the object's appearance caused by factors such as illumination and pose. Developments in computer vision suggest that it may be ...

This paper examines the processing of visual information beyond the creation of the early representations. A fundamental requirement at this level is the capacity to establish visually abstract shape properties and ...

Stimuli outside classical receptive fields significantly influence the neurons' activities in primary visual cortex. We propose that such contextual influences are used to segment regions by detecting the breakdown of ...

We present MikeTalk, a text-to-audiovisual speech synthesizer which converts input text into an audiovisual speech stream. MikeTalk is built using visemes, which are a small set of images spanning a large range of mouth ...

A typical robot vision scenario might involve a vehicle moving with an unknown 3D motion (translation and rotation) while taking intensity images of an arbitrary environment. This paper describes the theory and implementation ...

This paper describes the progress made towards tracking an object visually using a PIN diode attached to a dual mirror deflection system which enables the PIN diode to "optically point" to any position in two-space. A ...

Recent trends in OS research have shown evidence that there are performance benefits to running OS services on different cores than the user applications that rely on them. We quantitatively evaluate this claim in terms ...

The intent of this paper is to convey one idea central to the structure of a natural language parser currently under development, the notion of wait-and-see strategies. This notion will hopefully allow the recognition of ...

We present a simple, efficient, and self-contained construction of a wait-free regular register from Byzantine storage components. Our construction utilizes a novel building block, called 1-regular register, which can be ...

Part I of this paper describes some of the new functions in the system. The discussion is seasoned here and there with parenthetical code fragments that may be ignored by readers unfamiliar with PLANNER. Part II discussed ...

In this thesis, we detail an approach to extracting key information in medical discharge summaries. Starting with a narrative patient report, we first identify and remove information that compromises privacy (de-identifi ...

Applications that combine live data streams with embedded, parallel,and distributed processing are becoming more commonplace. WaveScriptis a domain-specific language that brings high-level, type-safe,garbage-collected ...

Excerpts from a talk given by Tomaso Poggio in Tübingen on the opening ofthe Werner Reichardt Centrun für Integrative Neurowissenschaften, December 8, 2008.

Decentralized systems, such as distributed hash tables, are subject to the Sybil attack, in which an adversary creates many false identities to increase its influence. This paper proposes a routing protocol for a distributed ...

We have implemented in simulation a prototype language for the Connection Machine called CL1. CL1 is an extrapolation of serial machine programming language technology: in CL1 one programs the individual processors ...

What plans are like depends on how they're used. We contrast two views of plan use. On the plan-as-program-view, plan use is the execution of an effective procedure. On the plan-as-communication view, plan use is like ...

An algorithm is presented which provides a way of telling what a given trihedral corner will look like if viewed from a particular angle. The resulting picture is a junction of two or more lines each labelled according to ...

We prove several decidability and undecidability results for the satisfiability/validity problem of formulas over a language of finite-length strings and integers (interpreted as lengths of strings). The atomic formulas ...
