  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Yuille, A.L. (1987-05-01)
    Shape from Shading, Occlusion and Texture are three important sources of depth information. We review and summarize work done on these modules.
  • Weinshall, Daphna (1990-10-01)
    This paper discusses the relationship between the shape of the shading, the surface whose depth at each point equals the brightness in the image, and the shape of the original surface. I suggest the shading as an ...
  • Freeman, William T.; Torralba, Antonio (2002-09-01)
    The goal of low-level vision is to estimate an underlying scene, given an observed image. Real-world scenes (e.g., albedos or shapes) can be very complex, conventionally requiring high dimensional representations which ...
  • Freeman, William T.; Zhang, Hao (2002-01-10)
    We introduce a new method to describe, in a single image, changes in shape over time. We acquire both range and image information with a stationary stereo camera. From the pictures taken, we display a composite image ...
  • Singhose, William (1990-03-01)
    This paper describes a method for limiting vibration in flexible systems by shaping the system inputs. Unlike most previous attempts at input shaping, this method does not require an extensive system model or lengthy ...
  • Torralba, Antonio; Murphy, Kevin P.; Freeman, William T. (2004-04-14)
    We consider the problem of detecting a large number of different classes of objects in cluttered scenes. Traditional approaches require applying a battery of different classifiers to the image, at multiple locations and ...
  • Sides 21 
    Greenblatt, Richard; Sordillo, Donald A. (1966-08-01)
    SIDES 21 produces a graph consisting of the locations of lines which comprise the sides of either a geometric solid or a plane figure. The representation is in floating point mode, suitable for subsequent processing. The ...
  • Winograd, Terry (1970-05-01)
    A recurrent topic of interest in the theory of automata has been the possibility of self-reproducing automata, particularly those which could reproduce globally through an application of a algorithm. In such a device, the ...
  • Lozano-Perez, Tomas (1986-06-01)
    This paper presents a simple and efficient algorithm, using configuration space, to plan collision-free motions for general manipulators. We describe an implementation of the algorithm for manipulators made up of ...
  • Fearing, Ronald S. (1984-11-01)
    A method is presented for stably grasping 2 dimensional polygonal objects with a dextrous hand when object models are not avaiable. Basic constraints on object vertex angles are found for feasible grasping with two fingers. ...
  • Singer, Neil C.; Seering, Warren P. (1993-05-01)
    A method is proposed for deriving dynamical equations for systems with both rigid and flexible components. During the derivation, each flexible component of the system is represented by a "surrogate element" which ...
