  • Beal, Jacob; Gilbert, Seth (2003-12-17)
    We present an algorithm to store data robustly in a large, geographically distributed network by means of localized regions of data storage that move in response to changing conditions. For example, data might migrate away ...
  • Taycher, Leonid; Darrell, Trevor (2001-09-01)
    Visibility constraints can aid the segmentation of foreground objects observed with multiple range images. In our approach, points are defined as foreground if they can be determined to occlude some {em empty space} in the ...
  • Lieberman, Henry; Hewitt, Carl (1981-10-01)
    In previous heap storage systems, the cost of creating objects and garbage collection is independent of the lifetime of the object. Since objects with short lifetimes account for a large portion of storage use, it's ...
  • Gordon, Steven J.; Seering, Warren P. (1988-05-01)
    A light stripe vision system is used to measure the location of polyhedral features of parts from a single frame of video camera output. Issues such as accuracy in locating the line segments of intersection in the image ...
  • McAllester, David Allen (1982-04-01)
    RUP (Reasoning Utility Package) is a collection of procedures for performing various computations relevant to automated reasoning. RUP contains a truth maintenance system (TMS) which can be used to perform simple ...
  • McIntosh, Harold V. (1968-01-01)
    REC/8 is a CONVERT program, realized in the CTSS LISP of Project MAC, for compiling RED expressions into the machine language of the PDP-8 computer. Since the compilation consists in its majority of subroutines calls (to ...
  • Edwards, D.J.; Minsky, M.L. (1963-11-01)
    This paper will report new developments and recent improvements to DDT. "Window DDT" now will remember undefined symbols and define them on a later command. Using sequence breaks, it can change the contents of memory while ...
  • Sinha, Pawan (1995-04-21)
    The processes underlying the perceptual analysis of visual form are believed to have minimal interaction with those subserving the perception of visual motion (Livingstone and Hubel, 1987; Victor and Conte, 1990). ...
  • Grimson, W. Eric L.; Lozano-Perez, Tomas (1985-06-01)
    This paper discusses how sparse local measurements of positions and surface normals may be used to identify and locate overlapping objects. The objects are modeled as polyhedra (or polygons) having up to six degreed ...
  • Poggio, Tomaso; Vetter, Thomas (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- ...
  • Ullman, Shimon; Basri, Ronen (1989-08-01)
    Visual object recognition requires the matching of an image with a set of models stored in memory. In this paper we propose an approach to recognition in which a 3-D object is represented by the linear combination of 2-D ...
  • Basri, Ronen (1992-12-01)
    A scheme for recognizing 3D objects from single 2D images is introduced. The scheme proceeds in two stages. In the first stage, the categorization stage, the image is compared to prototype objects. For each prototype, ...
  • Marr, David (1974-12-01)
    The recognition of sharp edges from edge- and bar-mask convolutions with an image is studied for the special case where the separation of the edges is of the order of the masks' panel-widths. Desmearing techniques are ...
  • Dror, Ron O.; Edward H. Adelson,; Willsky, Alan S. (2001-10-21)
    This paper describes a machine vision system that classifies reflectance properties of surfaces such as metal, plastic, or paper, under unknown real-world illumination. We demonstrate performance of our algorithm for ...
  • Beyer, Terry (1968-09-01)
    In this paper we study recognition of topological invariant properties of patterns by use of finite, rectangular 2-dimensional, interactive arrays of finite state automata (hereafter called modular arrays). The use of ...
  • Nagao, Kenji; Grimson, Eric (1995-04-22)
    In this paper we describe a new efficient algorithm for recognizing 3D objects by combining photometric and geometric invariants. Some photometric properties are derived, that are invariant to the changes of illumination ...
  • Grimson, W. Eric; Huttenlocher, Daniel P.; Alter, T. D. (1992-07-01)
    Many object recognition systems use a small number of pairings of data and model features to compute the 3D transformation from a model coordinate frame into the sensor coordinate system. With perfect image data, these ...
  • Torralba, Antonio; Sinha, Pawan (2001-07-25)
    We propose a scheme for indoor place identification based on the recognition of global scene views. Scene views are encoded using a holistic representation that provides low-resolution spatial and spectral information. The ...
  • Huttenlocher, Daniel P.; Ullman, Shimon (1987-01-01)
    This paper presents an approach to recognition where an object is first {\\it aligned} with an image using a small number of pairs of model and image features, and then the aligned model is compared directly against ...
  • Marill, Thomas (1989-09-01)
    We present an approach to the problem of recognizing three-dimensional objects from line-drawings. In this approach there are no models. The system needs only to be given a single picture of an object; it can then ...
