  • Brooks, Rodney A.; Flynn, Anita M.; Marill, Thomas (1987-08-01)
    We report on experiments with a mobile robot using one vision process (forward motion vision) to calibrate another (stereo vision) without resorting to any external units of measurement. Both are calibrated to a velocity ...
  • Edelman, Shimon; Weinshall, Daphna (1989-08-01)
    We explore representation of 3D objects in which several distinct 2D views are stored for each object. We demonstrate the ability of a two-layer network of thresholded summation units to support such representations. Using ...
  • Bullwinkle, Candace (MIT Artificial Intelligence Laboratory, 1977-03)
    This paper summarizes the design and implementation of the "semantics" module of a natural language undertanding system for the personal assistant domain. This module includes mappings to deep frames, noun phrase referencing ...
  • Attardi, Giuseppe; Simi, Maria (1981-08-01)
    Omega is a description system for knowledge embedding which incorporates some of the attractive modes of expression in common sense reasoning such as descriptions, inheritance, quantification, negation, attributions ...
  • Barber, Gerald; Jong, Peter de; Hewitt, Carl (1983-04-01)
    Present day computer systems cannot implement much of the work carried out in organizations such as: planning, decision making, analysis, and dealing with unanticipated situations. Such organizational activities have ...
  • Steck, Harald; Jaakkola, Tommi S. (2003-02-25)
    In this paper, we present an approach to discretizing multivariate continuous data while learning the structure of a graphical model. We derive the joint scoring function from the principle of predictive accuracy, which ...
  • Grimson, W. Eric L. (1985-08-01)
    The need for intelligent interaction of a robot with its environment frequently requires sensing of the environment. Further, the need for rapid execution requires that the interaction between sensing and action take ...
  • Farid, Hany; Adelson, Edward H. (1998-09-01)
    The image of an object can vary dramatically depending on lighting, specularities/reflections and shadows. It is often advantageous to separate these incidental variations from the intrinsic aspects of an image. Along these ...
  • Ullman, Shimon (1991-12-01)
    This paper presents a model for the general flow in the neocortex. The basic process, called "sequence-seeking," is a search for a sequence of mappings or transformations, linking source and target representations. The ...
  • Niyogi, Partha (1995-05-12)
    In most classical frameworks for learning from examples, it is assumed that examples are randomly drawn and presented to the learner. In this paper, we consider the possibility of a more active learner who is allowed ...
  • Horn, Berthold K.P. (1979-05-01)
    The shape of a continuous surface can be represented by a collection of surface normals. These normals are like a porcupine's quills. Equivalently, one can use the surface patches on which these normals rest. These ...
  • Williamson, Matthew M. (1995-09-07)
    This thesis presents the design, construction, control and evaluation of a novel force controlled actuator. Traditional force controlled actuators are designed from the premise that "Stiffer is better''. This approach ...
  • Lieberman, Henry; Hewitt, Carl (1980-09-01)
    Tinker is an experimental interactive programming system which integrates program testing with program design. New procedures are created by working out the steps of the procedure in concrete situations. Tinker displays ...
  • Strat, Thomas M. (1978-03-01)
    In order to perform image analysis, one must have a thorough understanding of how images are formed. This memo presents an algorithm that produces shaded perspective images of terrain as a vehicle to understanding the ...
  • Dowson, Mark; Waltz, David (MIT Artificial Intelligence Laboratory, 1971-06)
    The VIRGIN program will interpret pictures of crack and shadow free scenes by labelling them according to the Clowes/Huffman formalism. This paper indicates methods of extending the program to include cracks and shadows ...
  • Baker, Henry G. Jr. (MIT Artificial Intelligence Laboratory, 1977-01)
    Shallow binding is a scheme which allows the value of a variable to be accessed in a bounded amount of computation. An elegant model for shallow binding in LISP 1.5 is presented in which context-switching is an environment ...
  • Brooks, Michael J.; Horn, Berthold K.P. (1985-01-01)
    Well-known methods for solving the shape-from-shading problem require knowledge of the reflectance map. Here we show how the shape-from-shading problem can be solved when the reflectance map is not available, but is ...
  • Witkin, Andrew P. (1980-11-01)
    The problem of using image contours to infer the shapes and orientations of surfaces is treated as a problem of statistical estimation. The basis for solving this problem lies in an understanding of the geometry of ...
  • Ikeuchi; Katsushi (1980-03-01)
    An algorithm is proposed for obtaining local surface orientation from the apparent distortion of surface patterns in an image. A spherical projection is used for imaging. A mapping is defined from points on this image ...
  • Horn, Berthold K.P. (1970-11-01)
    A method will be described for finding the shape of a smooth apaque object form a monocular image, given a knowledge of the surface photometry, the position of the lightsource and certain auxiliary information to ...
