  • Dorr, Bonnie J. (1989-06-01)
    This report introduces an implemented scheme for generating target- language sentences using a compositional representation of meaning called lexical conceptual structure. Lexical conceptual structure facilitates two crucial ...
  • Lee, John J. (2008-04-07)
    LIBPMK is a C++ implementation of Grauman and Darrell's pyramid match algorithm. This toolkit provides a flexible framework with which developers can quickly match sets of image features and run experiments. LIBPMK provides ...
  • Shim, Keun Sup; Cho, Myong Hyon; Lis, Mieszko; Khan, Omer; Devadas, Srinivas (2011-05-02)
    Directory-based cache coherence is a popular mechanism for chip multiprocessors and multicores. The directory protocol, however, requires multicast for invalidation messages and the collection of acknowledgement messages, ...
  • Sobalvarro, Patrick (1988-02-01)
    Garbage collector performance in LISP systems on custom hardware has been substantially improved by the adoption of lifetime-based garbage collection techniques. To date, however, successful lifetime-based garbage ...
  • McAllester, David; Siskind, Jeffrey (1991-12-01)
    Lifting is a well known technique in resolution theorem proving, logic programming, and term rewriting. In this paper we formulate lifting as an efficiency-motivated program transformation applicable to a wide variety ...
  • Christoudias, Chris Mario; Morency, Louis-Philippe; Darrell, Trevor (2003-04-18)
    Statistical shape and texture appearance models are powerful image representations, but previously had been restricted to 2D or simple 3D shapes. In this paper we present a novel 3D morphable model based on image-based ...
  • Richards, W.A. (1981-08-01)
    A lightness scale is derived from a theoretical estimate of the probability distribution of image intensities for natural scenes. The derived image intensity distribution considers three factors: reflectance, surface ...
  • Forbus, K. (1977-05-01)
    The perception of surface luster in achromatic single view images seems to depend on the existence of regions with source-like properties. These regions are due to the interaction of specular component of the surface's ...
  • Moore, David; Olson, Edwin; Huang, Albert (2009-09-02)
    We describe the Lightweight Communications and Marshalling (LCM) library for message passing and data marshalling. The primary goal of LCM is to simplify the development of low-latency message passing systems, targeted at ...
  • Chockler, Gregory; Malkhi, Dahlia (2004-04-22)
    We propose light-weight lease primitives to leverage fault-tolerant coordination among clients accessing a shared storage infrastructure (such as network attached disks or storage servers). In our approach, leases are ...
  • Sarachik, Karen B. (1992-10-01)
    This paper presents a detailed error analysis of geometric hashing for 2D object recogition. We analytically derive the probability of false positives and negatives as a function of the number of model and image, ...
  • Moses, Yael; Ullman, Shimon (1991-05-01)
    Different approaches to visual object recognition can be divided into two general classes: model-based vs. non model-based schemes. In this paper we establish some limitation on the class of non model-based recognition ...
  • Fahle, Manfred (1989-11-01)
    Dichoptic presentation of vernier stimuli, i.e., one segment to each eye, yielded three times higher thresholds than binocular presentation, mainly due to uncorrelated movements of both eyes. Thresholds allow one to ...
  • Minsky, Marvin L. (1968-03-01)
    This memorandum is a first draft of an essay on the simplest "learning" process. Comments are invited. Subsequent sections will treat, among other things: the "stimulus-sampling" model of Estes, relations between Perceptron-type ...
  • Minsky, Marvin; Papert, Seymour (1967-01-01)
    The central theme of this study is the classification of certain geometrical properties according to the type of computation necessary to determine whether a given figure has them.
  • Vetter, Thomas; Poggio, Tomaso (1995-03-01)
    The need to generate new views of a 3D object from a single real image arises in several fields, including graphics and object recognition. While the traditional approach relies on the use of 3D models, we have recently ...
  • Minsky, Marvin; Papert, Seymour (1968-10-01)
    This is a reprint of page proofs of Chapter 12 of Perceptrons, M. Minsky and S. Papert, MIT Press 1968, (we hope). It replaces A.I. Memo No. 156 dated March 1968. The perceptron and convergence theorems of Chapter 11 are ...
  • Eberman, Brian; Brock, David L. (1991-01-01)
    A Whole-Arm Manipulator uses every surface to both sense and interact with the environment. To facilitate the analysis and control of a Whole-Arm Manipulator, line geometry is used to describe the location and trajectory ...
  • Griffith, Arnold K. (MIT Artificial Intelligence Laboratory, 1971-04-02)
    The line proposer P%PROPOSE1 is described in the first part of this memo. It makes use of links provided by the J%JOIN program, in proposing possibly missing lines in a line drawing of simple plane-faced objects. The ...
  • Griffith, Arnold K. (MIT Artificial Intelligence Laboratory, 1971)
    A line verifier is presented which, given the co-ordinates of the end points of the hypothesized line, returns a (possibly) more accurate version of the end points, together with an estimate of the probability that there ...
