  • Barber, Gerald R. (1981-02-01)
    This paper is a compendium of the ideas and issues presented at the Chatham Bars Workshop on Office Semantics. The intent of the workshop was to examine the state of the art in office systems and to elucidate the ...
  • Hildreth, Ellen C. (1991-06-01)
    We present a model for recovering the direction of heading of an observer who is moving relative to a scene that may contain self-moving objects. The model builds upon an algorithm proposed by Rieger and Lawton (1985), ...
  • Tappen, Marshall F.; Freeman, William T.; Adelson, Edward H. (2002-09-01)
    We present an algorithm that uses multiple cues to recover shading and reflectance intrinsic images from a single image. Using both color information and a classifier trained to recognize gray-scale patterns, each image ...
  • Hildreth, Ellen C.; Ando, Hiroshi; Anderson, Richard; Treue, Stefan (1991-12-01)
    We address the computational role that the construction of a complete surface representation may play in the recovery of 3--D structure from motion. We present a model that combines a feature--based structure--from- ...
  • Marill, Thomas (1998-03-01)
    Any three-dimensional wire-frame object constructed out of parallelograms can be recovered from a single perspective two-dimensional image. A procedure for performing the recovery is given.
  • McCarthy, J. (1959-03-30)
    This memorandum is a continuation of Memo 8.
  • McCarthy, J. (1959-03-13)
    The attached paper is a description of the LISP system starting with the machine-independent system of recursive functions of symbolic expressions. This seems to be a better point of view for looking at the system than the ...
  • Hollerbach, John M. (1980-06-01)
    An efficient Lagrangian formulation of manipulator dynamics has been developed. The efficiency derives from recurrence relations for the velocities, accelerations, and generalized forces. The number of additions and ...
  • Rahimi, A.; Morency, L.-P.; Darrell, T. (2001-05-07)
    We develop a class of differential motion trackers that automatically stabilize when in finite domains. Most differ-ential trackers compute motion only relative to one previous frame, accumulating errors indefinitely. We ...
  • Hollerbach, John M.; Suh, Ki C. (1986-01-01)
    Methods for resolving kinematic redundancies of manipulators by the effect on joint torque are examined. When the generalized inverse is formulated in terms of accelerations and incorporated into the dynamics, the ...
  • McIntosh, Harold V. (1968-01-01)
    REEX is a CONVERT program, realized in the CTSS-LISP of Project Mac, for carrying out the McNaughton-Yamada analysis algorithm, whereby a regular expression is found describing the words accepted by a finite state machine ...
  • Verri, Alessandro; Poggio, Tomaso (1986-09-01)
    Many problems of early vision are ill-posed; to recover unique stable solutions regularization techniques can be used. These techniques lead to meaningful results, provided that solutions belong to suitable compact ...
  • Poggio, Tomaso; Voorhees, Harry; Yuille, Alan (1985-04-01)
    We consider edge detection as the problem of measuring and localizing changes of light intensity in the image. As discussed by Torre and Poggio (1984), edge detection, when defined in this way, is an ill-posed problem ...
  • Bawden, Alan (1988-06-01)
    Constructing self-referential systems, such as Brian Smith's 3-Lisp language, is actually more straightforward than you think. Anyone can build an infinite tower of processors (where each processor implements the ...
  • Zucker, Steven W.; Stevens, Kent A.; Sander, Peter T. (1982-05-01)
    The Gestalt studies demonstrated the tendency to visually organize dots on the basis of similarity, proximity, and global properties such as closure, good continuation, and symmetry. The particular organization imposed ...
  • Shashua, Ammon; Navab, Nassir (1994-06-01)
    We propose an affine framework for perspective views, captured by a single extremely simple equation based on a viewer-centered invariant we call "relative affine structure". Via a number of corollaries of our main ...
  • Jarudi, Izzat N.; Sinha, Pawan (2003-03-01)
    The central challenge in face recognition lies in understanding the role different facial features play in our judgments of identity. Notable in this regard are the relative contributions of the internal (eyes, nose and ...
  • Horn, Berthold K.P. (1987-09-01)
    Before corresponding points in images taken with two cameras can be used to recover distances to objects in a scene, one has to determine the position and orientation of one camera relative to the other. This is the ...
  • Nevins, Arthur J. (1974-01-01)
    The splitting of a problem into subproblems often involves the same variable appearing in more than one of the subproblems. This makes these subproblems dependent upon one another since a solution to one may not qualify ...
  • Gennert, Michael A.; Negahdaripour, Shahriar (1987-06-01)
    Optical flow is the apparent (or perceived) motion of image brightness patterns arising from relative motion of objects and observer. Estimation of the optical flow requires the application of two kinds of constraint: ...
