  • Torre, V.; Poggio, T. (MIT Artificial Intelligence Laboratory, 1983-03)
    We present several results characterizing two differential operators used for edge detection: the Laplacian and the second directional derivative along the gradient. In particular, (a)we give conditions for coincidence of ...
  • Brooks, Martin; Ginsparg, Jerrold (1973-01-01)
    As originally proposed, perceptrons were machines that scanned a discrete retina and combined the data gathered in a linear fashion to make decisions about the figure presented on the retina. This paper considers differential ...
  • Blanchard, David C. (MIT Artificial Intelligence Laboratory, 1976-08)
    This paper describes a scheme for providing low-level control of a multi-link serial manipulator. The goal was to achieve adaptive behavior without making assumptions about the environment.
  • Saund, Eric (1987-01-01)
    This paper presents a method for using the self-organizing properties of connectionist networks of simple computing elements to discover a particular type of constraint in multidimensional data. The method performs ...
  • Weinshall, Daphna (1989-05-01)
    Structure from motion often refers to the computation of 3D structure from a matched sequence of images. However, a depth map of a surface is difficult to compute and may not be a good representation for storage and ...
  • Stein, Gideon P.; Shashua, Amnon (1998-12-01)
    We describe a new method for motion estimation and 3D reconstruction from stereo image sequences obtained by a stereo rig moving through a rigid world. We show that given two stereo pairs one can compute the motion of the ...
  • Heel, Joachim (1990-03-01)
    This paper presents a method for the estimation of scene structure and camera motion from a sequence of images. This approach is fundamentally new. No computation of optical flow or feature correspondences is required. ...
  • Marr, D.; Ullman, S. (1979-06-01)
    The construction of directionally selective units and their use in the processing of visual motion are considered.
  • Shimizu, Hiroaki; Poggio, Tomaso (2003-08-27)
    The capability of estimating the walking direction of people would be useful in many applications such as those involving autonomous cars and robots.We introduce an approach for estimating the walking direction of people ...

  • Negahdaripour, Shahriar; Horn, Berthold K.P. (1987-01-01)
    We address the problem of recovering the motion of a monocular observer relative to a rigid scene. We do not make any assumptions about the shapes of the surfaces in the scene, nor do we use estimates of the optical ...
  • Stein, Gideon P.; Shashua, Amnon (1996-12-01)
    We describe a new direct method for estimating structure and motion from image intensities of multiple views. We extend the direct methods of Horn- and-Weldon to three views. Adding the third view enables us to solve ...
  • Nagao, Kenji; Horn, Berthold (1995-12-01)
    Novel algorithms for object recognition are described that directly recover the transformations relating the image to its model. Unlike methods fitting the typical conventional framework, these new methods do not ...
  • Kahn, Kenneth M. (1978-06-01)
    Director is a programming language designed for dynamic graphics, artificial intelligence, and naﶥ users. It is based upon the actor or object oriented approach to programming and resembles Act 1 and SmallTalk. ...
  • Kahn, Kenneth M. (1979-12-01)
    Director is a programming language designed for dynamic graphics, artificial intelligence, and use by computer-naﶥ people. It is based upon the actor or object oriented approach to programming and resembles Act 1 ...
  • Negahdaripour, Shahriar; Horn, Berthold K.P. (1985-02-01)
    In this paper, we show how to recover the motion of an observer relative to a planar surface directly from image brightness derivatives. We do not compute the optical flow as an intermediate step. We derive a set of ...
  • Negahdaripour, Shahriar (1985-08-01)
    In this paper, we derive a closed form solution for recovering the motion of an observer relative to a planar surface directly from image brightness derivatives. We do not compute the optical flow as an intermediate ...
  • Negahdaripour, Shahriar; Yuille, Alan (1986-03-01)
    In this paper, we solve the problem of recovering the motion of an observer relative to a surface which can be locally approximated by a quadratic patch directly from image brightness values. We do not compute the ...
  • Taalebinezhaad, M. Ali (1990-03-01)
    This work introduces a direct method called FIXATION for solving the general motion vision problem. This Fixation method results in a constraint equation between translational and rotational velocities that in combination ...
  • Rich, Charles; Waters, Richard C. (MIT Artificial Intelligence Laboratory, 1981-12)
    Simplifying assumptions — everyone uses them but no one's programming tool explicitly supports them. In programming, as in other kinds of engineering design, simplifying assumptions are an important method for dealing with ...
